Tata Group have announced investment of over £4 billion to build a UK gigafactory, their first outside of India. At 40GWh it would create up to 4,000 new jobs and thousands across the wider supply chain. It would be a huge boost to the UK automotive sector, and a significant step towards meeting the government 2030 target to end the sale of petrol and diesel cars. And with the expansion of Ultra-Low Emission Zones in London and across the UK, the demand for electric vehicles will only grow further and faster. On the other hand, Tata Steel are close to securing a £500 million package from the UK government to secure its long-term future, with a requirement to commit to building electric arc furnaces to reduce carbon emissions from steel production.

Firstly, a big thank you to all those involved in the Instrumentation, Analysis and Testing Exhibition which took place in May at the Silverstone Race Circuit, which was a huge success and attracted its highest visitor attendance to date. In other EIS events, Fatigue 2024 preparation is advancing with abstracts submitted and reviewed, keynote speakers announced, and the full programme being worked on. In addition, several EIS seminars have successfully taken place, one of which has led to the formation of a Net Zero Group that will aim to be a platform and catalyst for future innovations.

Throughout these last few months, we have seen wildfires, flooding and hurricanes across the globe with every increasing frequency and uncertainty around when these events will occur and what they may leave in their wake. Knowledge and understanding of how we can predict, mitigate and cope with such events is a serious challenge, one that engineering needs to be at the forefront of.

A technical failure of UK air traffic control for just a few hours took place one day in August and led to severe disruption with cancelled flights, stranded passengers and a knock-on effect that lasted several days with planes at locations they were not supposed to be. The cause was said to be from a single piece of data in a flight plan that was wrongly input. This highlights potential flaws within such automated systems and the serious consequences that can arise. In other flying news, although now flying in space, the Indian Space Research Organisation landed Chandrayaan-3's Vikram on lunar soil, the first to ever land near the lunar south pole. Particularly impressive when you consider the budget for the Chandrayaan-3 mission was much less than that of some Hollywood

University applicants have had their A level results, which have seen a steep fall compared to the last two years where they received teacher-assessed grades in the absence of taking exams. As always, I hope all those who have applied to university, whether their first choice, insurance choice or through clearing, have found a degree programme and university that is best for them. Universities themselves face certain challenges in terms of their funding, large inflation rises means that student fees are worth significantly less, approximately a £2,500 shortfall per student compared to the 2012 fee cap of £9,000. In addition, the loss of EU funds poses a real risk to research funding, jobs, collaboration and recruitment, and is something that must be addressed.

The technical paper in this issue provides an overview of profilometry-based indentation, which has the potential to offer real advantages in terms of providing bulk mechanical properties using limited material with increased turnaround times compared to conventional methods. A technical article on real-time thermal correction in complex load-bearing structures assessed using finite element modelling is presented, with a follow-up article revealing the experimental results due in a later Engineering Integrity publication. In addition, a piece on the importance of mastering and leveraging artificial intelligence gives some insight into its potential for enhancing productivity, efficiency and innovation.

Lastly, a huge thank you to Nick Richardson, who has stepped down from his role as a Trustee and Director of the EIS – we all wish him all the very best in retirement.

Obituary: John Atkinson

Prof Emeritus John Atkinson CEng FIMMM

10 August 1946 – 20 February 2023

John was born in Kingston-upon-Hull, in Yorkshire, UK, and attended Hull Grammar School. He then studied Metallurgy at Aston University, Birmingham, UK, obtaining a BSc Hons degree. An MSc course in physics of materials at Bristol University, UK, was followed by a CEGB-sponsored PhD at The Cavendish Laboratory, University of Cambridge, UK. His thesis was on the ‘Fatigue Mechanisms in Copper Single Crystals'.

On completion in 1973, he was invited to apply for a research officer position in the materials division at the CEGB research laboratories in Leatherhead, Surrey, UK, (known as CERL). He worked there, on a variety of power plant problems associated with cracking for nearly 20 years, until privatisation of the electricity supply industry in the late 80s led to a move to academia, where he took a professorial post in the engineering department at Sheffield City Polytechnic, UK.

He was a member of the International Co-operative Group on Environmentally Assisted Cracking (ICGEAC) from 1978 to 2008 (whilst at CERL, NPTEC and Sheffield Hallam University) and spent nine years as Chair of the Low Alloy Steels (LAS) Task Group, with duties on the Executive Committee.

Sheffield City Polytechnic were granted a university charter to become Sheffield Hallam University in 1993 and John was able to transfer some of his equipment at this time, as CERL was also closed down in 1993 by National Power. At Sheffield Hallam he had a busy life, developing teaching material on up to 15 modules at BEng and MSc level, as well as carrying out contract research on cracking issues for the relocated power companies.

Over a period of 15 years he generated a research/ consultancy income of £1m and helped to boost the 2001 RAE rating in materials from 3a to 5 of the university, equal at that time to Imperial College London. He supervised six PhD students to completion and, during Science Week, gave several public lectures in Sheffield on nuclear power issues.

John retired in 2015 and ceased his consultancy work within the power industries to pursue his hobby of restoring rusty old Porsche 356 cars and to spend time with his family – wife Sue, children Jane and Neil and five grandchildren.

John Atkinson was a respected voice in cracking, then later moved into academia where he advocated for quality research and supervised PhD students.

News from the Women's Engineering Society

Back in 2022 when we chose the theme for International Women in Engineering Day 2023 (INWED) and our Top 50 Women in Engineering Awards (WE50), we couldn’t have predicted how important that theme would become.

In a world where the war in Ukraine sees no end, wildfires are continuing across the world, women’s safety concerns are still ignored, and the climate emergency continues to grow, our chosen theme of safety and security and INWED hashtag #makesafetyseen couldn’t be more appropriate.

posting on the day including Jessica Ashley (Miss England), Jodie Sloss (racing driver) and Bethany Holroyd (Top 100 Most Influential Women in Construction 2022).

• 25 community partners,

• Almost 30k visitors to the INWED website in June and

• A whopping 782m potential reach on Twitter!

Alongside the social media campaign, hundreds of events were held around the world all celebrating International Women in Engineering Day. There were podcasts and online events showcasing engineers from industries across the board including building, manufacturing, civil, structural and computing. Face-to-face events were held in locations as far and wide as Hong Kong, Korea, Australia and Africa all with a focus on the 2023 hashtag #makesafetyseen.

Keeping people safe is a key part of engineering, but often goes unnoticed. The women in this year’s WE50 list are a truly amazing group. Their work often goes unseen yet is key to keeping us all safe and secure. Winners were chosen from across the engineering industry. Through creating safer neighbourhoods via improved street design, improving body armour for women serving in the forces, or developing fire strategies for heritage buildings, the idea of safety and security encompasses all our lives.

Each year the judges are always amazed at the breadth and talent of the nominations. This year the judges were particularly impressed with how many of the women had overcome barriers both personally and professionally to forge a career in what is still a male-dominated environment. Many of our winners were mentors for other women, spending time actively challenging gender stereotypes and promoting diversity.

Alongside the WE50, another highlight of the WES calendar is the INWED campaign, which continues to grow with women and allies all over the world joining in on social media.

The statistics show how big a campaign this has become:

• #INWED23 trended at number 1 on Twitter in the UK.

• Almost 84k impressions on @inwed1919 Twitter, an increase on 2022.

• 276,550 impressions across all INWED social platforms.

• 25 social media ambassadors from around the world

Seeing how many organisations and individuals were keen to get involved shows just how important this campaign is not only in inspiring the next generation of engineers but also in supporting women working in industries where they are still in the minority. Women still struggle to break into what is perceived as a maledominated industry and the barriers to women entering and staying in engineering are hard to break down. A lack of flexible working, incorrectly fitting PPE, and unequal pay are all issues that women engineers face today and need to be addressed.

That’s why campaigns such as INWED are still so relevant today and why as an organisation we continue to champion our vision of an engineering industry that employs the diversity of the society it serves to solve the biggest societal issues of our time.

Technical Paper:

Overview of Profilometry-based Indentation: Plastometry and its Industrial Usage

Plastometrex Ltd, 204 Science Park, Milton Road Cambridge CB2 0GZ, UK.

Author correspondence:


This paper includes a review of the current state-ofthe-art in a technique for extracting the (quasi-static) stress-strain relationship of a metallic sample from an indentation experiment, as well as an industrial case study using the technique to map the stress-strain properties of a forged part. The technique, called profilometry-based indentation plastometry (PIP), uses a large (either 1 mm or 0.5 mm radius) spherical indenter to create a residual indent under relatively high applied loads (kN range). The indent profile is measured, and iterative finite element method (FEM) simulation of the indentation is carried out to converge on the true stress-strain curve of the indented material (with the indent profile as the target outcome). Commercial products are now available that automatically complete indentation, profilometry and convergence upon Voce plasticity parameter values, which describe the full stress-strain curve within a few minutes. The review covers the technique’s advantages as an indentation-based technique, firstly in the mapping of samples and secondly in giving insight into the direction and sense of anisotropy from the breakdown in radial symmetry. The case study demonstrates the application of the technique in both of these areas for characterising a forged part, comparing the results from PIP to conventional uniaxial testing. It is shown that the scale of PIP unveils local inhomogeneity unable to be detected by tensile testing, where these differences can be linked to the prior plastic strains introduced during forging. Additionally, anisotropy is detected by PIP relating to aligned FeNiAl precipitates that give a sense of the strength and direction of the anisotropy.

Keywords: Indentation; Stress-strain curves; Profilometry; Inverse FEM.

1. Introduction

Attempts to extract meaningful plasticity characteristics from indentation tests on metals have a long history. These characteristics are fully described by the relationship between the applied stress and the resultant plastic strain, which is conventionally obtained via a uniaxial tensile test, or in some cases via a uniaxial compression test. However, while this relationship also dictates the outcome of an indentation test, inferring the former from the latter is far from simple. The stress

and strain fields are naturally much more complex, and evolve substantially, during an indentation operation, compared with the situation during a uniaxial test. However, progress has been made recently and a viable methodology has been developed. Known as profilometry-based indentation plastometry (PIP), the methodology involves measurement of the residual indent profile and then iterative finite element modelling (FEM) of the indentation operation, to infer the stress-strain relationship that is most consistent with that profile. While this is relatively simple in principle, the methodology must be optimized in several respects if accurate stress-strain curves are to be obtained in an efficient and robust manner. It may also be noted that most early attempts to implement this kind of approach were based on use of the loaddisplacement plot as the target outcome [1–6] but this approach suffers from a lack of uniqueness where different stress-strain curves produce identical loaddisplacement curves. It has now become clear that using the residual indent profile offers a number of important advantages[7–10], including alleviating the uniqueness issue.

Other requirements include the need to deform a relatively large volume of material that is representative of the bulk. This requires the effects of all the microstructural features that contribute to the plasticity response to be captured, i.e. the indent must be large relative to the grain size. In addition, the indent must generate relatively large plastic strains to ensure that the range of strains of interest in a conventional tensile test are covered during indentation. There are also a number of important advantages[3–5, 11, 12] in using a spherical indenter. These include ease of manufacture, reduced risk of damage and a high sensitivity to the detection of anisotropy in the material via a lack of radial symmetry in the indent profile. In terms of practical usage, it is clear that an integrated facility is needed, in which creation of the indent, measurement of its profile and the iterative FEM are under automated software control and are completed within a short period (a few minutes). An example of such a facility is shown in Figure 1. It incorporates a stylus profilometer, has a load capability of about 10 kN and 'uses interchangeable silicon nitride spheres of either 0.5 mm or 1 mm radius. Samples with a yield stress of up to about 2.5 GPa can be tested[13], with software protection in place to abort any test started on a material with values in excess of this limit. This allows testing of virtually any metal used for structural engineering purposes.

2. Operation of an Indentation Plastometer

2.1. Basic Operation

The key issues involved in implementation of the PIP procedure are covered in a recent review article[14]. One point to note is that the elastic constants of the material and the indenter, the Young’s modulus and Poisson ratio, are required for the FEM simulation. While the focus is on plasticity, elastic deformation takes place during the test and does affect the outcome (residual indent shape). For the indenter, the elastic constants are defined by the indenter material and for the specimen, the sensitivity to these elastic constants is relatively small and they need only be specified to a precision of about 10–15%. Furthermore, since the modulus is determined by the electrostatic interactions between the atoms in the structure and shows very little sensitivity to microstructure (unlike plasticity, which is strongly influenced by microstructure) all that is required is knowledge of the base metal.

Once the elastic constants have been specified, indentation has been carried out, the profile has been measured and the iterative FEM algorithm has been implemented, the “solution” is obtained as a true stress –true plastic strain relationship, in the form of a set of three parameter values in a constitutive law. For PIP testing, the Voce law is used, as shown in Equation (1) where σ is the (true) stress, ε is the (true) strain, σY is the yield stress, σ s is a saturation stress and ε0 is a characteristic strain (for the approach of the stress to its saturation level). When implemented in the FEM model, these stresses and strains are von Mises values.

Figure 1: Image of an indentation plastometer, with the key components labelled.
Figure 2: Measured and (best-fit) modelled indent profiles[10], for two penetration depths, for (a) as-received Cu and (b) annealed Cu.

A typical comparison between experimental and bestfit modelled indent profiles is shown in Figure 2 for as-received and annealed copper (with two different penetration depths in each case – i.e. two different applied loads). A corresponding comparison is shown in Figure 3 between the nominal stress – nominal strain plots obtained by tensile testing these materials and those from the indentation-derived true stress – and true strain relationship (with FEM simulation needed to obtain the post-necking part of the curve).

4, which shows two maps of yield stress and ultimate tensile stress (UTS) across parent-weld transition regions.

Such information cannot be obtained via tensile testing and, while it would be common to carry out hardness tests on this type of scale, hardness numbers are just semi-quantitative indicators of the resistance to plastic deformation and should not be used in any quantitative way. In contrast to this, these PIP-derived stress-strain relationships (as a function of location) can be used in FEM simulation of how the weld region would respond under service conditions.

2.3. Detection of Anisotropy

It is quite common for metallic samples to exhibit at least some (plastic) anisotropy – i.e. for the stressstrain curve to be different when tested in different directions – for example, in the two in-plane directions and the through-thickness direction of a rolled plate. This commonly arises from crystallographic texture – a non-random distribution in the orientations of individual grains. One attraction of PIP is that it has a high sensitivity to the detection of in-plane anisotropy, in the form of a lack of radial symmetry in the indent. Indent profiles are routinely taken in more than one direction and any significant differences between them are automatically flagged to the operator. An example[16] is shown in Figure 5.

2.2. Mapping of Stress-Strain Characteristics

PIP testing offers many advantages over conventional uniaxial testing. These include a capability for the mapping of properties on a relatively fine scale. The deformed region is typically a disk of about 0.5 mm radius and a thickness around 0.2 mm, so mapping on a scale of mm is feasible. An example[15] is presented in Figure

The two SEM micrographs of the indent (in transverse and parallel planes relative to the growth direction of an additively manufactured superalloy component) do show that one of them is not radially symmetric. Rather more sensitively, the profiles are noticeably different for the asymmetrical case, with the pile-up height greater in the “softer” direction – which in this case is the growth direction. The PIP-derived stress-strain curve is effectively a direction-averaged one, lying between those obtained via tensile testing in the two principal directions. Although it is not at present possible to obtain stressstrain curves for different directions from a PIP test, the presence and sense of the anisotropy can be detected. Since the monitoring of anisotropy is often very difficult via uniaxial testing, this is a valuable capability.

3. An Industrial Case Study

3.1. Objectives

It is common for components to have large variation in properties due to their processing. This is widely seen in all industries, for example when large plastic strains are imposed during forming, or when there are localised differences in thermal histories such as near a weld. When the scale of such inhomogeneity is smaller than the scale of a tensile test, such that the variations have little effect, it becomes difficult to fully characterise a component. Often hardness testing would be used instead, but this gives only a semi-quantitative indication of a material’s plasticity properties. For the purposes of making confident engineering decisions, such as predicting component life as part of an engineering critical assessment (ECA) where plasticity properties are required, a different method is needed for characterisation, which can give localised plasticity parameters. PIP testing is able to bridge this gap, giving a full stress-strain curve from an indentationbased test, and is therefore ideally suited to characterising parts with localised plastic inhomogeneity. The objective of this case study was to detect localised variations in the plasticity parameters of a section of an aluminiumbased forging, pictured in Figure 6. Traditional uniaxial testing, both tensile and compressive, was carried out and compared to PIP testing on a sectioned slice of the forging.

3.2. Methods

3.2.1. Microstructural Examination

Microstructures were examined using optical and SEM microscopy, with EDX for compositional analysis. An investigation was also made into the phases present, using a Philips X’Pert PW3020 X-ray diffractometer, in combination with the Highscore programme, and the Inorganic Crystal Structure Database (ISCD) was used to identify phases formed on the free surfaces. The Highscore search was limited to phases containing Al, Ni and Fe.

3.2.2. Uniaxial Testing

Uniaxial testing was carried out both in tension and compression for the Al-based forging. Figure 7 shows a photo of a section of the forging, indicating the approximate locations from which tensile and compression samples were cut, and the corresponding numbering system. The numbers for the compression samples are also used to indicate the locations of indents. Round tensile samples were machined in accordance with ASTM E8, and compression samples were 5 mm diameter by 5 mm height. All tests were carried out on an Instron 3367 conventional mechanical testing frame. Full details of the conditions used for tensile and compressive testing are available in previous publications[5, 10, 17, 18] .

3.2.3. PIP Testing

PIP results were measured using a PLX Benchtop Plastometer, pictured in Figure 1. Multiple indents were carried out, and the compression sample locations in Figure 7 give a rough indication of their location. The input Young’s modulus of the forging was taken to be 69 GPa, and the Poisson’s ratio to be 0.3.

After preparation to P2500 grit using silicon carbide paper, and polishing using 1 μm diamond paste, the sectioned Al-forging was placed on the load cell of the plastometer. A 1 mm diameter indenter ball was used to indent the material in several locations with a fixed load of 1.5 kN. A contacting stylus profilometer, with a depth resolution of about 1 μm, was used to carry out profilometry of the indents.

Tilt correction functions were applied to the raw data, based on the far-field parts of the scan being parallel. Iterative finite element analysis is then applied to obtain the true stress-strain curve, by optimising for three plasticity parameters in a constitutive law. Confidence intervals are also presented based on how unique the experimental residual indent profile is. These procedures are carried out automatically under software control. Comparisons with the uniaxial testing data related to nominal stress v. nominal strain curves, for which simple analytical conversions from the true form were used. These are only valid while the stress and strain fields within the gauge length are uniform, which is the case up to the onset of necking (the UTS).

3.3. Results and Discussion

3.3.1. Microstructure

The microstructure of the forging was unusual and varied between different locations within the component. The grain structure was relatively fine (~30150 μm) throughout, although there were certainly local variations in grain size and shape. More striking was the presence of a significant volume fraction (~7 %) of the second phase in the form of relatively coarse (~5-10 μm) precipitates. These showed a strong tendency to: (a) align so that their longer axis is in a particular direction and (b) be collected into parallel sets of “stringers”, as can be seen in Figure 8.

This kind of structure is strongly indicative of the effect of relatively large plastic strains being imposed in the direction concerned. It is likely that the component was produced in a two-stage process, being initially cast to a suitable shape, and then plastically deformed during a forging process, with the magnitude and directionality of the plastic strain varying between different locations.

The composition of the second phase was obtained using EDX in the SEM, with the beam focused on individual particles. The overall average composition of the alloy was obtained similarly, with the beam scanned over a large area. Both sets of compositions are shown in Table I, where it can be seen that the second phase mainly contains Al, Fe and Ni. It was identified by X-ray diffraction as Fe0.7Ni1.3Al9, with a typical spectrum shown in Figure 9. (This phase has a complex crystal structure, giving many low intensity peaks: those at high Bragg angles are virtually impossible to identify, but several at lower angles are indexed in Figure 9 and it seems likely

that only this phase is present, apart from the Al matrix, or other phases present at levels below 1%.) The (relatively low) intensity of the second-phase peaks is consistent with it being present at a level of about 7 vol%.

This alloy is thus effectively a particulate reinforced MMC. The FeNiAl phase is both stiffer and harder than the matrix, so a significant increase in both stiffness and hardness of the material is expected to result from its presence[18]. Furthermore, the alignment evident in Figure 8(a) is expected to create some (in-plane) anisotropy. In addition, differences in the magnitude of the plastic strain in different parts of the forging are also expected to affect the mechanical properties, with work hardening of the matrix expected to raise the yield stress in parts subjected to higher strains. Care is, however, needed here, since it is possible that recrystallization, leading to marked softening, could have occurred after forging, depending on the thermal history.

There is clearly interest in exploring variations in microstructure between different parts of the forging. Some information of this type can be seen in Figure 10, which shows several optical micrographs, together with an indication of their location on the section shown. The alignment of the FeNiAl precipitates allows the broad nature of the plastic flow field during forging to be visualized, giving at least some idea of the probable distribution of plastic strain. Most regions have clearly been subjected to relatively high strains, although there appears to be a region in the lower central part of the section (near image 27) that may have been a “dead zone” that remained relatively undeformed from the original cast structure.

3.3.2. Uniaxial Testing

Tensile stress-strain curves are shown in Figure 11(a), with the labels corresponding to the locations shown in Figure 7. These curves are all very similar, with a yield stress of around 420 MPa and a UTS value of about 450 MPa. It is also evident that there is little or no systematic difference between the individual curves. This is in fact unsurprising in view of the information in Figure 10. While there are certainly indications there that some locations had been subject to different plastic strains during manufacture, these tensile tests were interrogating relatively large volumes of material, over which such local variations would probably have had little effect.

Illustrative compressive stress-strain curves are shown in Figure 11(b). These relate to two pairs of samples, both from the base region, one from a location near the inner surface and one near the outer surface – see Figure 7. Even on the relatively coarse scale of the compression samples, significant variations are apparent. The yield stress is noticeably higher for the outer region (samples 9 and 10), which may be associated with that region having experienced higher prior strains during manufacture. This type of relevant information is lost in the tensile test results of Figure 11(a).

3.3.3. PIP Testing

PIP tests were carried out in different locations, with significant differences between some of the outcomes. Variations were observed from point to point, consistent with observed differences in local microstructure. As an example, derived plots are shown in Figure 12 for two locations, compared in each case with the tensile curves of Figure 11(a). While there are locations for which the indent profiles reflect the tensile test outcomes, and these were in the majority, in other locations the outcome indicated a slightly different response with a higher yield stress. This outcome highlights the capability of PIP testing to obtain stress-strain characteristics on a much finer scale than is possible by conventional tensile or compressive testing.

PIP testing also detected marked anisotropy, although it varied from point to point and was not systematic across the component. The anisotropy in this component does not arise from texture, but from preferential alignment and inhomogeneous distribution of a hard “reinforcement”. It could be regarded as a (metal matrix) composite material and in general composites often exhibit strong anisotropy.

Figure 11: (a) Tensile nominal stress-strain curves and (b) compressive nominal stress-strain curves, taken from the locations shown in Fig. 7. Figure 12: Conventional and PIP-derived tensile stress-strain curves, with the indents located at (a) point 5 and (b) point 9 (as shown in Fig. 7).

The kind of effect that can arise during indentation of such material is illustrated by the SEM micrograph of an indent shown in Figure 13. The alignment of the “stringers” in this case is from top left to bottom right. Small “undulations” have been created around the rim of the indent, which are primarily associated with the anisotropy (possibly influenced in some cases by a relatively large grain size in these regions – there is some rotation of individual grains in the rim area during indentation). Variations such as these have the potential to influence measured indent profiles. This is illustrated by Figure 14, which shows four profiles across another indent, oriented at four different angles. Such variations are not normally observed. An average can be taken of such profiles, and this is likely to lead to a direction-

anisotropy, without the need for machining separate samples.

3.3.4. Applications of PIP Testing

The ability to generate accurate stress-strain curves from a simple indentation test opens many applications for PIP testing. As has been shown, it can be used to map properties over inhomogeneous components such as forgings or those containing welds. It can also be used for quality control or quality assurance purposes, as a replacement for tensile testing or hardness testing, as well as for rapid quality checks during manufacture to optimise further processing on the component. The turnaround times are significantly lower than for tensile testing, where the requirement for CNC machining often leads to days or weeks of a delay, and therefore the cost per test is also significantly lower.

As an indentation-based technique, an added advantage is that it can be applied to high-value assets in the field for in-situ monitoring of properties. Applications in this space include the assessment of properties in oil and gas pipelines, especially if such assets are to be repurposed for example for the transport of hydrogen. In this context, it can be used as a non-destructive test method to support engineering critical assessments.

4. Summary

The following points can be noted regarding PIP technology:

a) Integrated facilities are now commercially available, with the complete set of operations under automated control, so an understanding of their capabilities and features is starting to become highly significant. It seems likely that usage of the technology will expand considerably over the next few years.

b) If “bulk” properties are required, then it is important to mechanically interrogate a “representative” (manygrained) volume, and to create plastic strains in the approximate range of up to several tens of %. These requirements lead, in turn, to a need for an indenter radius of around 0.5–1 mm, a penetration depth of a few hundred μm and a load capability in the kN range.

c) Using the profile of the residual indent as the target outcome, rather than the load-displacement plot, offers many advantages. It is easier from an experimental point of view, its sensitivity to the stress-strain curve is greater and it allows detection and exploration of sample anisotropy.

averaged stress-strain curve that will be acceptably accurate. However, such variations can already be used to obtain information about local anisotropy, for example the direction parallel to the “stringers” is hardest as its profile has the lowest peak pile-up. In this way, a single indent has identified the presence and sense of

d) PIP can be applied to a wide range of industrial scenarios, offering capabilities such as mapping of properties over surfaces and detecting anisotropy. Some examples are presented here. Such information cannot be obtained using conventional uniaxial testing. In addition, the cost of a PIP test is significantly lower and the turnaround time significantly faster than the conventional tensile test where coupons must be prepared through subtractive manufacturing.

News from British Standards

BSI’s standards committee area for engineering design, specification and verification, TPR/1 (Technical product realization) – whose Subcommittee for the BS 8887 standards on Design for Manufacture, Assembly, Disassembly and End-of-life processing (MADE) is chaired by Professor Brian Griffiths – has been as busy as ever so far this year.

2023 has seen a number of national committee initiatives in the TPR/1/7 area move forward. One in particular – new national work with the lighting sector on the remanufacture of luminaires – has been formally accepted onto the BSI work programme. The proposed new British Standard, a code of practice BS 8887-221, will be moving through its formal standards development stages over the course of the rest of the year.

National Subgroup TPR/1/7/4, which brings together leading UK lighting remanufacturers, lighting industry trade associations and professional bodies, as well as relevant academic institutions, will refine the document and see it through its public comment, committee approval and publication stages.

Also on remanufacturing – which is the process by which a previously sold, worn, or non-functional product can be rebuilt, recovered or reused – another national Subgroup, TPR/1/7/5, has been meeting with the medical devices sector in order to explore options for new standards on sustainable product design and sustainable manufacture. The discussions are still at the exploratory stage but TPR/1/7/5 reports growing interest from across the healthcare sector.

On the international standards front, TPR/1/7 was pleased to welcome the publication of ISO 8887-2, the international vocabulary for MADE. The new standard sets out the terms and definitions across the ISO 8887 area allowing for future parts of the series to be developed at the international level. ISO/TC 10 WG20, which is converting a number of parts of the national BS 8887 series into international (ISO) standards, is run by the UK and chaired by Brian Griffiths.

The first part of the series, ISO 8887-1, was published in 2017. New work is currently under way to convert BS 8887-3 – guidance on the selection of an appropriate end-of-life design strategy – into a new international standard, ISO 8887-3.

And finally, back to the national standards work programme. Brian Griffiths’ TPR/1/7 main Subcommittee will be meeting in the autumn to review and discuss all of the standards and projects under its remit. The aim of the meeting – which will be a workshop-style event at BSI’s offices in Chiswick, West London – will be to flesh out future standards needs as well as allocating responsibilities for existing and ongoing work items and initiatives.

With all of this ongoing work and activity, the TPR/1area committees are always looking for new committee members and experts to join its standards drafting groups, national committees, and international working groups. Further general information on taking part in BSI’s standards work can be found at:

2023 saw the UWR Formula Student team transition into the second phase of the Wolf VII project. With the 2022 event having provided valuable knowledge regarding the static events, the team felt well prepared to tackle the 2023 competition as a Formula Student class entry.

The competition itself took place at Silverstone immediately after the F1 Grand Prix weekend, from the 27th to the 30th July. Four long days that saw some of the worst July weather for years challenged the 60+ university teams that brought either petrol or EV cars to the contest.

Thursday brought the first challenge of the week; static events. Cost & Manufacturing was the first judged session of the day, which was immediately followed by the Engineering Design event. Costing and engineering design were both a success, with good feedback on the team’s approach to costing structure, price-based design choices and general design aims and understanding. We also received useful feedback regarding our designs and where they could be improved or iterated upon.

Taking the feedback from the judges in our stride, the car was swiftly brought to scrutineering, the first of which being tech scrutineering. This initial stage is usually very difficult to overcome, as there is a vast array of rules and compliances the car must adhere to. However, Wolf VII passed this stage in our second attempt (with many teams needing four or more visits to scrutineering), and

all other static scrutineering stages were completed on the first run. After the car was weighed, coming in at 221kg, the dynamic scrutineering took place. Tilt, noise, and brake tests were all passed first time, with flying colours, and the car was fully approved to compete in dynamic events by Friday afternoon.

Three dynamic events took place on the Saturday: Acceleration, Skidpad and Autocross. Mixed conditions were forecast for the day, so the call was made to exploit the dry start of acceleration and skidpad. UWR were the second car out to the acceleration area and put in a solid baseline time of 5.2 seconds, then smashed this first time with a 4.7 second run. We were the first team under the 5-second barrier and secured a spot in the run-offs. To make the best of the conditions, the car was swiftly wheeled to the skidpad area, and a solid time of 7.1s was put into the books. Just before the autocross laps, the car went out for the run-offs in wet conditions. A mechanical error resulted in a missed gearchange, unfortunately not gaining any extra points. Autocross was completed in very wet conditions, with a best time of 1:20.4, placing the team 12th in that event.

Sunday saw the final dynamic event of the weekend, endurance. This event is a 28-lap test of reliability and teamwork, with a driver change requiring solid coordination and communication. Wolf VII went first of the qualified cars and rocketed to a fast start. The first stint went very well, and the pace was looking very

for endurance. As is the nature of the competition, the team went into full diagnostics mode, and determined a poor sensor reading to be the culprit. We were justifiably heartbroken with the endurance result, but the team have taken it on the chin and are now in the planning stage for Wolf VIII, with the aim of making an even bigger comeback for the next competition!

UWR Formula Student placed 17th of 64 FS-Class entries, with a best dynamic event finish of 4th position (acceleration). This is our second-best performance in 7 years of competitions, and our best result since our 11th place finish in 2017. We are incredibly proud of the car that has been produced in this project and are immensely thankful for the support received from the Engineering Integrity Society and all the sponsors who made Wolf VII possible.


News from the Institution of Mechanical Engineers

Why mastering AI is crucial for the engineers of tomorrow

As the world becomes increasingly driven by technology, the role of artificial intelligence (AI) in shaping the future of engineering cannot be overstated. Engineers stand to benefit greatly from mastering AI skills. However, there can be some doubt around how it can exactly be integrated to the day-to-day workflows of engineers.

AI has the potential to revolutionise mechanical engineering by enhancing productivity, efficiency and innovation. Its applications are diverse, ranging from design optimisation and predictive maintenance to autonomous systems and robotics.

Why engineers can unlock economic potential

To effectively build AI models and systems, engineers need a range of skills and knowledge, including digital skills, maths and domain/business expertise. Traditional research in any field applies techniques from mathematics and statistics to a certain domain or problem. Machine learning in its simplest form is statistical and numerical problems solved iteratively with computational mathematics. Software engineering is about solving a domain or business problem with the help of computers and custom developed tools. However, by combining these skills, engineers can work with data in ways that have given rise to the field of data science – which also includes AI model development. Data science is a multidisciplinary field that involves extracting insights and knowledge from data using various techniques and methodologies. It combines elements of mathematics, statistics, computer science and domain expertise to analyse and interpret large and complex datasets.

The engineers of tomorrow are also data scientists

Engineers of tomorrow can also be data scientists without having to leave the engineering field behind. Most engineering problems involve working with data in spreadsheet tools like Excel. This often involves running mathematical calculations on this data, such that certain values are calculated for solving design, maintenance, or operational problems. What sets engineers with data science skills apart is their deep domain expertise and strong mathematical background. This gives them an advantage, allowing them to create AI tools that don't exist yet or work with engineering datasets that data scientists from another field may not be able to use. However, to unlock this potential, engineers need to learn new skills and work with more tools.

The need for digital skills and programming knowledge

While engineers can certainly use tools like Excel for various tasks, it is not the most suitable tool for building complex AI models. Excel has limited computational and data processing power and does not provide any tools for building AI models. In these cases, programming languages like Python are necessary for engineers to handle complex or large

datasets. The main point to takeaway is engineers need a diverse skill set that includes digital proficiency, mathematical aptitude, and domain expertise. By combining these skills, engineers can delve into the field of Data Science, extracting valuable insights from complex datasets. By embracing AI and honing their digital and programming skills, engineers can position themselves at the forefront of innovation, shaping the future of their field. The engineers of tomorrow have a unique opportunity to leverage the power of AI, driving advancements and making a significant impact in the increasingly technology-driven world.

The National Adaptation Programme (NAP3) has been launched.

Dr Laura Kent, Public Affairs and Policy Advisor at the Institution of Mechanical Engineers said: "The National Adaptation Programme (NAP3) published today is a step in the right direction amidst the alarming increase in temperatures and other extreme weather events both nationally and worldwide. The urgency to adapt has never been more evident. We are pleased with the establishment of a new coordinating body within the Cabinet Office and the collaborative efforts with the Met Office to enhance accessibility to climate data. This is a vital move to effectively plan and retrofit our building stock as well as a wide range of vital infrastructure assets, to ensure their resilience to future higher temperatures and increasingly frequent, prolonged and severe heatwaves. The time for action is now, and we must swiftly implement comprehensive strategies across a wide range of sectors to safeguard lives, livelihoods and productivity."

Commenting on publication of NAP3, IMechE Fellow Dr Tim Fox, Chair of the Climate Change Adaptation Working Group said: “The Institution of Mechanical Engineers and wider engineering profession are focused on helping government, academia, industry and civil society develop solutions to the challenges of adapting to climate change. The record-breaking temperatures being experienced in many parts of the world at the moment put a sharp focus on the urgent need to deliver these solutions. We stand ready to work with the new cross-government Climate Resilience Board to help support the continued health, comfort, safety, food and nutritional security, productivity and economic well-being of the nation.”

News from the Institute of Measurement and Control


The National Metrology Skills Alliance (NMSA) was established in 2021 on the back of work started by the Midlands Centre for Data Driven Metrology (MCDDM), which had identified the need for a national framework outlining skills and knowledge in the field of metrology.

From that work, a cross-industry group was formed, with the primary aim to develop and promote a recognised standard for professional metrologists.

The NMSA was formalised as an official InstMC Special Interest Group (SIG) in 2022 with representatives from academia and industry including MCDDM, Jaguar Land Rover, Coventry University, BAE Systems, AWE, Suriflo, Reliance Precision, Sellafield, NPL and Rolls-Royce. Working groups were set up to focus on drafting the core standard and the subject specific annexes covering topics including core, flow, manufacturing, control and force.

With regular SIG meetings and cross-industry collaboration throughout 2023, the core standard documents were created and have now been put through the process of both alpha and beta testing. This has resulted in the standards and subject/sector-based annexes being split into three sections:

NMSA 1 – Core Metrology Skills – with four categories aimed at different skill levels: Foundation (for nonmetrologists), Level 1 (Practitioners, Technical/Skilled), Level 2 (Senior Technician/Team Leader/Skilled) and Level 3 (Approver, Managing/Expert).

NMSA 2 – Subject/Industry Sector Skills – split into the following sectors: Manufacturing, Flow, Force, Control and Future.

NMSA standards are structured to help both individuals and organisations. Individuals can use the standards to look at their own skills in relation to their work objectives as part of their career development. Perhaps using it to create a gap analysis, identifying where skills need to be further developed. Organisations can utilise the standards to monitor the skills of their teams. They could also use the information to create role profiles, either for existing staff or to help construct job adverts to recruit externally. Internal training can also be tailored according to the standards, in line with specific learning outcomes that are recognised by industry.

Earlier this year, a call went out for volunteers to assist with beta testing the standards, prior to publication. The NMSA invited contribution from a range of companies, organisations and universities and were delighted with the high volume of responses. Support was voiced from industry, manufacturing, research centres, measurement OEMS and manufacturers as well as users, all expressing their willingness to be involved and how the standards could work for them.

Following a successful testing phase, the Core, Manufacturing & Flow Standards are now close to publication and will be available, ready to use, later in the year through the InstMC website.

A working group for ‘Qualifications’ (NMSA 3) is currently being set up and is open for volunteers who would like to take part and offer their expertise.

If you have any questions or would like to get involved in any aspect of the NMSA, please email NMSA@instmc. org. For all the latest information on the NMSA, visit skills_alliance.

Groundbreaking project to bring high-value 3D printing to UK manufacturings

Technology being developed by a global consortium of companies and academic institutions could revolutionise the use of industrial additive manufacturing – also known as 3D printing – in the UK, bringing the advanced manufacturing of high-value components for key industries to the country for the first time.

The Evo One ‘large-format additive manufacturing’ (LFAM) project – which involves 3D printing experts Evo-3D; the National Manufacturing Institute Scotland (NMIS) operated by the University of Strathclyde and part of the High Value Manufacturing Catapult (HVMC); Rolls-Royce; materials supplier Filamentive; software developer AI Build; and energy technology company Baker Hughes – are developing a 3D printer system that could make UK manufacturers more competitive than their international peers. The initiative has received £1.1 million in funding from Innovate UK, the UK’s innovation agency.

LFAM is a commercial 3D printing technique that creates large volume polymer components, used in a variety of industries including aerospace, automotive, energy, and marine. While countries like the USA, Germany and China have embraced this approach, there are currently no manufacturers of large-format 3D printers in the UK and the country only accounts for around 5% of the global additive manufacturing market, which the UK government aims to increase to 8% by 2025.

Access to the right technologies will be a crucial part of achieving that aim, but existing LFAM systems have their limitations. These include slow build times, being unsuitable for high-value or high-integrity parts, operational complexity, use of unsustainable materials, and being unaffordable to small- and medium-sized companies.

The new product being developed through Evo One LFAM will address the challenges associated with these systems and cater to the specific needs of the UK market. The system’s design team is aiming to make it 60% more reliable, achieve a 50% increase in productivity, reduce training and maintenance costs by 30%, and cut material waste by 80%, among a range of other improvements.

On the project’s completion, Evo-3D will launch a spin-out business to commercialise the system, called RapidFusion, creating the UK’s first original equipment manufacturer (OEM) in LFAM. Its development would also create the foundation on which a new supply chain can be built, re-shore critical manufacturing capabilities, and help more UK manufacturers take advantage of the opportunities presented by Industry 4.0 – the fourth industrial revolution.

Megawatt charging speeds for electrified motorsports: from 5% to 85%

(SOC) in just under 90 seconds

The hofer powertrain battery team developed a fully functional high-voltage battery using a market-leading BMS system and fast-charging CCS DC wallbox available on the market at the time. The initial proof of concept (POC) involved installing it in a racing kart and subjecting it to a series of complex tests under load and with real road resistance, which significantly exceeded expectations. By simulating various driving situations with the highvoltage charging system, it was possible to determine the battery's and system's functionalities as well as the overall performance within the powertrain system, where all measurements confirmed the groundbreaking charging curve. The hofer powertrain BlueFire battery demonstrated extremely high cycle stability. In less than 90 seconds, the battery could be recharged successfully from 5–85% SoC (State of Charge). The LTO cells used for this purpose have proven to be particularly suitable for applications that require fast charging and discharging with high charging currents and have opened new possibilities for the future.

During this initial pilot project in pre-development, it became apparent that the new battery is ideal for 24-hour endurance races that rely on extremely short charging times. In addition, it can be variably scaled to fit different applications.

In the meantime, initial discussions with interested parties and investors have started with excellent responses. The engineers are currently focusing on increasing the already very high energy density in the cells of the BlueFire battery considerably while at the same time reducing the weight of these cells.


The University of Manchester lead innovation in clean hydrogen production

A new technology that offers a cost-effective way to produce synthetic gas and pure hydrogen with nearly zero direct carbon dioxide emissions will be developed and delopyed by an international team of scientists, led by The University of Manchester. The RECYCLE (REthinking low Carbon hYdrogen production by Chemical Looping rEforming) project will construct and test a fully integrated innovative hydrogen production pilot unit based at the University.

The technology uses special reactors called fixed bed reactors to convert different materials into hydrogen gas. The process also effectively captures and separates carbon dioxide. It offers a competitive solution for the production of low-carbon hydrogen using both natural gas, biobased streams and waste materials to provide low-cost hydrogen.

The £5.1 million collaborative project is funded by the Department for Energy Security and Net Zero as part of the Net Zero Innovation Portfolio (NZIP), and involves five world-leading industrial partners in the area of engineering for sustainable development, including Johnson Matthey, TotalEnergies, OneTech, Kent, Helical Energy and Element Energy.

In the recently published Powering Up Britain: Energy Security Plan, the UK government expects to have two gigawatts of low-carbon hydrogen production capacity in operation or construction by 2025 and 10 gigawatts in 2030, subject to affordability and value for money. The final demonstration of the project is planned for

the second half of 2024 in the pilot area of the James Chadwick Building at The University of Manchester.

Hardide Coatings awarded Innovate UK funding

Advanced surface coating technology company, Hardide Coatings has been awarded funding from Innovate UK to further study the flexural behaviour of the Hardide chemical vapour deposition (CVD) coatings under high static and cyclic loading conditions.

The funding has been awarded under Innovate UK’s Analysis for Innovators (A4I) Round 9 programme and will enable the company to understand better the influence of key coating characteristics on performance when subject to high static and cyclic loading conditions. This will enable the optimisation of the coating to solve technical challenges encountered in the power generation and hydrogen production and distribution sectors. In turn, this will support the UK’s net zero ambition while reducing waste generation and pollution through the development of longer-lasting equipment resistant to hydrogen attacks and reduced servicing, downtime and part replacement.

The study will be carried out in collaboration with the National Physical Laboratory (NPL) and is expected to be completed by spring 2024.

New Battery Intelligence could rapid charge electric vehicles 25 per cent faster, cutting holiday queues

The UK’s EV rapid charging network is under significant pressure – but new software could significantly reduce charging time and cut queues at motorway services.Elysia, the pioneering new battery intelligence company offering from WAE Technologies (WAE), draws on WAE’s unrivalled experience in high-performance batteries, gleaned from the sole supplier of batteries to ground-breaking electric motorsport series, as well as the design and development of batteries for road cars, electric hypercars and 1.4 MWh packs for 250 tonne mining trucks.

Its suite of algorithms can safely unlock extra performance from an electric vehicle battery, bringing a host of benefits for plug-in car makers, which in turn can be passed on to consumers, such as faster charging. With an estimated 12.6 million journeys set to be made by holidaymakers per week in summer, a significant number of which will be electric cars – EVs made up 17.9 per cent of new car sales in June, with last month showing a 40 percent increase in volumes over this time last year – charging demand is likely to exceed supply at points during holiday peaks.

However, Elysia estimates that a typical electric vehicle could rapid charge 25 per cent faster if it was equipped from the factory with its intelligent software, reducing the time spent on a charger by 10 minutes, alleviating queues and resulting in much more efficient use of the rapid charging network.

Novel numerical method for real-time thermomechanical correction in complex loadbearing and load-measurement applications

Author correspondence:,

Temperature variations within complex structures can present daunting engineering challenges in a wide range of applications and industries affecting safety and reliability of operations and the ability to achieve objectives. Advanced aeronautical research is no exception, and one particularly important topic is the requirement to obtain high-quality, reliable load data for novel flight vehicle development programmes using wind tunnel tests. This has motivated ARA to find a solution using the latest mathematical, computational and experimental techniques currently available, and will be the focus of this article.

Wind tunnel testing commonly involves the measurement of forces and moments on the test article using a strain gauge balance. This measures the strain of structural beams within the balance using strain gauges. A mathematical model relates the strains to applied forces and moments. Wind tunnel balances are mounted internally within the wind tunnel model and typically measure up to six components, consisting of forces and moments about three axes on the model. Loads can be measured on complete aircraft models, half models, control surfaces, stores and blown nozzles. The following analysis relates to an ARA-designed balance, used to measure forces and moments on a nozzle with air flowing through the internal structure as well as the external surfaces.

Temperature-related effects are the most common causes of error in strain measurements with

strain gauge balances used for wind tunnel load measurements. Ideally, wind tunnel (WT) balances equipped with of a number of strain gauges measure strain only in response to applied aerodynamic loads. However, strain gauge material, the lead wiring, as well as the balance material to which the strain gauge is applied, also respond to changes in temperature, which affects the strain measurement accuracy. Empirical

methods commonly used to minimise the steadystate temperature sensitivity include optimising the toplogy of the beams and gauge layout and by tuning the inter-gauge wiring. Nevertheless, these steady-state conventional methods based on a uniform temperature do not completely remove the thermally induced strain errors, which are often due to thermal gradients and changes of temperature with time.

Besides conventional methods that are used to minimise thermal effects on balance measurement readings, modelling can also be employed to gain a better understanding of the structural state of the balance induced by thermal changes.

At ARA, a novel thermal error reduction technique has been developed and employs computational analysis. The approach approximates the balance thermal and structural states for the purpose of real-time thermally induced strain prediction for balance operations during a wind tunnel test, providing a reasonable balance between accuracy and computational cost. For investigation and validation, the numerical thermal correction method was applied to an ARA bespoke balance (illustrated in Figure 1) for the testing of a dual-stream jet propulsion rig, where the balance measures aerodynamic loads of engine nozzles powered by high pressure air[1]

In the first phase of the research and ahead of the balance experimental test taking place in the ARA facility in summer 2023, the thermal correction method was assessed and verified using a finite element (FE) simulation of a realistic physical experiment. The FE model of the balance, shown in Figure 2, is built by importing the CAD model into the FE software ABAQUS CAE[2].

The FE balance model is made of UDDEHOLM RAMAX HH steel described in Table 1. Figure 3 depicts the boundary conditions and the thermal load applied to the FE balance.

The FE balance is clamped at its left side, called the “earth”, and is subjected to a time-dependant temperature distribution at the right side, or the “live”, in order to induce thermomechanical error. The physical WT balance includes a number of temperature sensors and strain

gauges. In real WT conditions, the thermal correction method uses the temperature values measured by the temperature sensors as inputs and outputs the thermally induced strain at each of the balance beams.

These strains are then further processed and translated into forces. Here, the temperature values were extracted from the FE analysis at the locations of the temperature sensors and utilised as inputs for the thermal correction method. Figure 4 compares the thermomechanical strain generated by the thermal correction method (solid line) with the FE results, (dashed line) at two different beams. Overall, the thermal correction method very closely follows the trend of the FE data over time, in particular

at the time = 1s where the absolute value of the applied temperature gradient is the highest (about 10 K).

The axial and side forces resulting from the thermal strain match the FE predictions, as shown in Figure 5. The method offers good approximation of timedependant loads and proves to be reliable in correcting balance measurements affected by thermal strain. In summary, a novel balance thermal correction method has been developed in order to correct balance

measurement readings due to temperature gradients during a WT test. In the first stage of the investigations, it was assessed using an FE analysis simulating a possible experimental scenario. The numerical method successfully predicted load errors induced by the thermal strain by only considering temperature inputs while balancing speed and accuracy. Coupled with calibration methods, the thermal correction method appears promising in providing insight into the balance thermal and strain state for live balance measurement corrections during WT tests. While the results presented give cause for cautious optimism, the problem of real-time thermal correction in complex load bearing structures is very challenging as it demands capturing thermally induced strain variations of an order of magnitude of 10-6 making the method sensitive to discrepancies in the exact positions of the temperature sensors and strain gauges and the accuracy of the time-dependant temperature measurements. In the second stage of the research, experimental tests on the balance will be conducted at ARA and the proposed thermal correction method will be validated against experimental data. The outcome will be reported in a follow-up article in this publication in the near future.

3D-Printed Jigsaws and Turkey

Whilst the title of this journal update could quite happily be the title of a sitcom, it does nicely capture the focus of my STEM outreach for the past six months.

Out of the blue I received an email from a colleague based in Turkey who wanted to provide STEM outreach to communities local to the Rolls-Royce offices in Antalya. Approximately 10 years ago a number of 3D jigsaws were designed and machined from aluminium by the apprentice academy in Derby, which are a collection of seven pieces that represent the modules from a jet engine. At events such as careers or STEM roadshows, the engines can be used to talk to students about the jet engine and they can have a go at constructing the engines against the clock or their friends and family. The engines have proved very successful and are in regular use.

been used for the shaft that holds all the pieces together and I also embedded some retaining metal nuts. The aluminium versions were quoted at around £400 each and whilst it is nice to hold something metal, the 3D printed equivalents cost just £15 each (most of which is the metal threaded rod).

Our first test of the engines was at an RAF family day in late July where they were used as if they were the original metal versions. Not only did they function as the metal ones do, but we were able to also introduce the concept of 3D printing at the same time and the potential benefits we can unlock for aerospace materials and manufacturing.

In parallel I have been hosting cohorts of work experience students now that schooling has returned to normality after the pandemic. Historically much of the experiences have had to be talking about the work rather than allowing them to do any (due to health and safety); however recently we have been working on some more practical examples for the students to undertake themselves during the week.

The offices in Turkey wanted to enquire about manufacturing the engine puzzles locally and, after some quotes received in the UK for metal conventional manufacturing of them, I had a brainwave: Why do they need to be machined from metal? Wouldn’t it be cheaper, just as a effective and cooler to 3D-print them?

I set about modifying the CAD files to make the engines printable (as some of the tolerances and fits needed to be changed) and we then manufactured two test engines from silver PLA. For longevity a bit of metal has

A particular favourite of the students is Charpy testing of chocolate bars and biscuits, which they are allowed to do themselves. We can demonstrate in a mildly destructive way the ability of a material to absorb deformation under a fixed set of impact criteria. The students also get to experience a shortened failure investigation to establish the series of events that led to a catastrophic overload of a paperclip.

As ever, if anyone is interested in knowing more about how they can get involved in STEM please do not hesitate to contact me or your local STEMnet contract holder.


New robots to provide remote medical treatment in hazardous environments

Game-changing robotics technology to provide remote medical treatment to casualties in high-risk emergency environments has been developed by researchers at the University of Sheffield.

Using medical telexistence (MediTel) technology, researchers from the university’s Advanced Manufacturing Research Centre (AMRC), Sheffield Robotics and Department of Automatic Control and Systems Engineering, have successfully created a mobile, robotic-controlled uncrewed ground vehicle (UGV), which boasts virtual reality (VR) capability, to enable medics and operators to assess critical casualties in hazardous environments, allowing them to perform a remote triage while also ensuring their safety.

The first-of-its-kind, fully integrated medical telexistence solution was developed in just nine months. It features two robotic arms that can effectively remotely operate medical tools to perform a critical initial assessment of a casualty within 20 minutes, including: temperature, blood pressure and heart rate checks; carry out a palpation of the abdomen and administer pain relief through an auto-injector – all while streaming real-time data to the remote operator.

The project was led by David King, Head of Digital Design at the AMRC and Sanja Dogramadzi, Professor of Medical Robotics and Intelligent Health Technologies at the Department of Automatic Control and Systems Engineering and Director of Sheffield Robotics.

maximum permitted temperatures (cooling of safetyrelevant assemblies), monitoring of thermal limits in closed-loop systems (thermal management system optimization), detection of temperature arrays at the system inlet and outlet (cooling capacity determination). Further applications for the M-THERMO3 16 are in the e-mobility sector like determination of temperature parameters of auxiliary units for system optimization and optimization of temperature distribution in the passenger compartment. It can also be used in the aerospace sector for altitude tests of engines in flight operations or for validation of fuel consumption and maintenance intervals of engines.

Humans to provide energy source for smart devices of the future

Scientists may have finally found a solution to effectively harvesting energy from humans into electrical energy. Researchers from the Institute of Thin Films, Sensors and Imaging (ITFSI) from the University of the West of Scotland (UWS) explored the use of the 3D graphene foam material Gii™ by Integrated Graphene as an active layer in an energy generator. The investigation aimed to transform mechanical energy wasted in nature into electrical energy that could be used to power small electronic devices and sensors in the booming global market for Internet of Things (IoT) technologies.

The research, published in ScienceDirect, shows that the force of a human footprint on a pressure-sensitive mat, equipped with Gii-TENG sensors, can produce enough energy to anonymously identify people entering or leaving a room. As well as providing a low-cost and energy-efficient solution to monitoring building occupancy, the mats could also help to optimize energy resources by, for example, controlling room temperature upon entrance or exit.

Mechanical energy is one of the most abundant and versatile energy sources available in nature. For around 20 years, triboelectric nanogenerators (TENGs) have been investigated as a technique for converting mechanical energy from our daily actions into usable electrical energy that can power both small IoT electronic devices

and sensors but also more power-hungry items such as electric cars and drones.

However, efforts to develop a commercially viable TENG have, to date, been hampered by issues relating to low durability, limited energy output and inefficiency. The addition of Gii™ to TENG has opened up a whole new world of possibilities due to its unique properties, including high surface area, porosity, light weight, and superior electrical properties. The energy autonomous, pressure-sensing nature of Gii-TENG has the potential to transform various aspects of our lifestyles, society and economy including, for example:

• Harvesting energy from sports such as golf, running, and tennis to power smart devices which generate performance data.

• Self-powered wearable biosensors for early diagnosis of health conditions including cardiovascular disease, gout and diabetes.

• Harvesting energy from cars on roads and people walking in the creation of smart cities.

• A smart energy solution for Industry 4.0.

• Extending the hovering time of drones, allowing transportation of parcels – and even people in the future – for longer distances and longer times.

New ICP Tiraxial Accelerometer

PCB Piezotronics (PCB) has released a new lowoutgassing ICP triaxial accelerometer, called the Model 356A19. The solution is the company’s latest addition to its portfolio of miniature, triaxial accelerometers and has been developed to enable accurate high-frequency measurements to 13kHz (±5%).

(10.2mm) cubical housing with a 1.5m integral cable to a four-pin ¼-28 pin connector. A 1.5m mating extension cable to the BNC plug termination is a supplied accessory.

Apex Dynamics introduce new hypoid gearboxes

Apex Dynamics UK we have recently expanded their range to include hypoid gearboxes. This is a natural progression to enhance their offering to customers, providing a wider range of products and potential performance applications. Their new high efficiency BKM Series of high-precision hypoid gearboxes offers high torque, superior accuracy, excellent radial load capacity and low backlash, all in a compact design that is fully compatible with any motor.

Hypoid gearboxes are a type of spiral bevel gearbox. In contrast to traditional bevel gearboxes, they have nonintersecting axes, meaning they are not parallel, but rather are offset from one another. This provides them with hyperbolic rather than conical geometry.

Due to the tooth design, there is a greater contact area, meaning higher torques and gear ratios are possible, delivering greater precision. Hypoid gearboxes are compact and also offer smoother running properties, have quiet operation and can achieve lower backlash ratings than traditional bevel or worm-type gearboxes. They tend to be used where speeds exceed 1000 rpm, or for lower speed applications that demand extreme smoothness or quietness.

Although hypoid gearboxes are currently a relatively small segment of the overall precision gear market, it is likely to grow faster than the general rate as a range of industries continue to see the benefits of the technology. This includes high-growth sectors such as robotics and automation. Recent research by industrial automation market specialist Interact Analysis forecasts the precision gear products market will expand by a compound annual growth rate of 7.7% between 2022 and 2027, climbing from $3.6 billion to $5.2 billion.

Key applications include the automotive industry, industrial machinery, robotics and automation, renewable energy systems, and power tools.

The transducer electronic data sheet (TEDS), which complies with IEEE 1451.4, is located within the sensor and includes data such as the serial number, sensitivity and last calibration date.

Due to its small size and wide frequency range, the 356A19 is well suited for modal and structural analysis, vibration testing in thermal vacuum environments, ESS and HALT/HASS testing of satellites, automotive internal combustion engine and electric vehicle powertrain development, vehicle systems NVH, and vibration testing in confined spaces or on small, lightweight objects.

The 356A19 features a hermetically sealed, 0.4in

With a variety of mounting, input and output options, the expansion was a natural step for existing and new customers that allows Apex to become even more competitive and keep up with market trends. Anyone purchasing a hypoid gearbox from Apex Dynamics UK is able to take full advantage of their five-year warranty, excellent lead times and high levels of customer service.

Group News

Durability & Fatigue Group

Over recent months a large part of our energies in the Durability and Fatigue Group have been devoted to preparations for the forthcoming Fatigue 2024 conference, in Cambridge. We are very pleased and excited by the programme which is coming together.

Over 100 papers are already confirmed but, at time of this publication, there is still space for just a few more, even though the abstract deadline is officially passed. There are also opportunities to sponsor and exhibit, so please get in touch with our Marketing & Events Manager if you are interested.

Meanwhile, the group continues to run a mixture of virtual and in-person meetings, aiming to find a good balance for ease of participation. Fatigue issues within the renewable sector continue to be a topic of discussion, as does durability in joining technologies, in which regard we are working towards a seminar on bolted joints.

Simulation, Test & Measurement Group

In March’s journal, I started off by saying how keen the EIS is to understand how people want to attend future events; that said, we still believe it’s important, more than ever, to offer the ability for people to attend events in person, rather than just online. Offering interesting locations and live demonstrations is something we are keen to do, and seminars are usually best experienced in person rather than virtually.

We want to ensure that seminars are not just click and listen but interactive, two-way forums that stimulate conversation and build communities of like-minded people, keen to learn from others and grow with the future! To keep the seminars stimulating, we will be exploring old and new techniques and are always keen to hear the hot topics you feel should be included.

The group is working hard to bring you interesting and relevant seminars that will hopefully resonate with all. AI, alternative fuel and autonomous vehicles are on the horizon, and this is an opportunity to revisit some previously covered topics with a fresh focus. It will be interesting to explore and discover; will products be changing what they are doing faster than we can measure it?

The question posed at the last EIS STMG meeting was whether we thought running more seminars on measurement carried value. The answer was a unanimous yes. In the current simulation-heavy climate, it is arguable that quality data collection is more important than ever before, as a simulation is only as good as the physical data that you feed it. AI systems will also run based on data collected, so data collection is as relevant as ever, despite the move to relying more heavily on simulation.

As a result, the EIS is currently looking at a series of seminars/webinars focused on first principles and basic understanding of measurement, which I hope will be finalised in the forthcoming months. I look forward to sharing this soon. We are also looking at presenting a series of case studies, successes and failures to Young Engineers with perhaps a panel of engineers to answer questions and provide help and guidance.

We are also aware we are dominated by members in the automotive sector and want to increase our membership to include other sectors.

Finally, as always, I wrap up the September journal with a thanks to all those who supported the Instrumentation, Analysis & Testing Exhibition, which once again was very well-attended with excellent exhibitor feedback. This year saw the largest number of attendees to date and it was great to bump into so many old friends at the Silverstone Circuit. Next year’s event will take place on 23 March 2024 and we hope to see many of you there.


Sound & Vibration Product Perception Group

Since the last journal issue in March 2023, the SVPP Group successfully held a seminar in April at the Institute of Advanced Automotive Propulsion Systems on the subject of Net Zero Vehicle Powertrain Engineering Design and Development Technology. More information on this seminar and future initiatives can be found on page 30, but suffice to say that

this was a very successful event with overwhelming support for further seminars in the future.

Consequently, there will be more offerings and activity from the EIS over the coming months and years, in what is a rapidly developing engineering field with some of its own unique challenges and technologies.

Alongside the Net Zero seminar the SVPP Group committee has also been working on ideas for a Sound Quality-themed seminar for 2024. Many years ago the SVPP would quite often run sound quality seminars and workshops based around aspects of the internal combustion engine and its loudness, harmonic content and impulsiveness etc. Many metrics and techniques evolved at the time to support the development of the internal combustion engine noise character and level, which were explored at numerous EIS seminars and workshops at the time.

As the automotive sector transitions to electric vehicles, there has been a re-emergence in interest in this subject, albeit with new designs and technologies. In general, the

environmental acoustic impact on human health from a range of noise sources is well-documented. In the progression towards net zero products and use of renewable energy generation, the soundscape in the environment is changing and in some respects significantly deteriorating. This presents an engineering challenge across a range of product sectors.

In bringing together engineers from industry and academia through seminars and workshops, we intend to facilitate the understanding and know-how to address the future netzero soundscape.

If you are interested in supporting our activities in the future, whether through the Net Zero or Sound Quality initiatives then please let myself or Sara Atkin (EIS Marketing & Events Manager) know.

The following companies are corporate members of the Engineering Integrity Society. We thank them for their continued support which helps the Society to run its wide-ranging events throughout the year.
