Simulation of the ballistic perforation of aluminum plates with Abaqus/Explicit Abaqus Technology Brief Summary

Key Abaqus/Explicit Features and Benefits

Background

 Mie-Grüneisen equation of state to model materials at high pressure  Johnson-Cook plasticity model that accounts for strain rate, thermal effects and compressibility  Johnson-Cook dynamic failure model within the Abaqus ductile damage initiation criterion for metals  Progressive damage framework
