Abstract
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.
