The strain rate considered by Bischoff was mainly focused on the 10-5~10 s-1 , where only few test data higher than 10 s-1 With the rapidly development of SHPB experimental technique in recently years, a number of valuable research results have been achieved in concrete at higher strain rate. Figure 2(b-d) summarizes the tested DIFσ of concrete reported between 1942 and 2015, and the strain rate ranged from 10-5 to 103 s -1. The result showed that the maximum DIFσ was around 4.0 for concrete. Since only a few studies achieved the DIFσ higher than 3.0, more work are needed for the dynamic compressive behavior of concrete at higher strain rate.
