摘要：
The initial results of an investigation into the dynamic behavior of copper C101 are presented. This study involved several experimental technicques; quasi-static, compressive Split Hopkinson Pressure Bar (SHPB), a modified Taylor test and a direct impact method. From these studies dynamic and static stress-strain curves were obtained. Numerical simulation was applied to the system using a variety plasticity models in a LS-DYNA environment. The results of the models were valicated by comparison with two selected experiments. Overall the study shows the essential need for cross-comparison of the materials parameters used and how the different techniuques yeild these fundamental parameters in differing ways.
