A Very Strain Rate Compression Test Using a Modified Split Hopkinson Pressure Bar Technique

摘要

A modified split-Hopkinson pressure bar (SHPB) technique is presented. The dynamic stress-strain behavior estimated by using the conventional and modified SHPB technique are compared. A computer simulation is also performed to study the dynamic material responses. It is suggested that the modified SHPB test proposed in this study can be successfully utilized to offer an experimental condition of a higher strain rate than that obtained from the conventional SHPB test.
