Dynamic Deformation Behaviors of High Performance Steels

Abstract:

The responses of three high strength steels under impact loading were examined, specifically on their strain rate dependence. Split Hopkinson pressure bar test was used in this study. Over a wide strain rate range, the Johnson-Cook model and modified Johnson-Cook mode were adopted to determine the strain rate hardening behavior of the materials. The group determined the material parameters for each metallic material tested. Obtained material parameters were used to predict the behavior of each steel at high strain rate region. The modified Johnson-Cook model was not able to represent well enough the plastic deformation behavior of steels, specifically the steel that exhibited strain softening behavior at high strain rate region.
