Numerical Simulation and SHPB Test Study for Some High Polymer

摘要

With the widening of the application field of the Split Hopkinson pressure bar (SHPB) experimental technique, there is the demand for better experimental equipment and higher experimental accuracy, so it is urgent to improve and optimize the SHPB experimental technique and numerical simulation is an important way. The SHPB tests of some high polymer specimen were performed at room temperature and high one. And by the finite element analysis software ABAQUS, the numerical simulation of impact compression behavior of experimental specimen were studied, and represented the stress waves shape, stress variation, stress-strain curves of it during the SHPB test. The temperature effects on impact simulation were investigated. Comparison with the experimental results, computational ones has better agreement, and it verifies that numerical simulation will be helpful to the optimal design of SHPB test.
