Abstract

The applicability of the polymer-steel sandwich structures has become a topic of interest over the last few years. To study the effect of polymers (which are well-known energy absorbers) on the performance of sandwich structures under blast loads, a set of experiments were carried out on circular polyurea-steel sandwich samples in a 3 Hopkinson bar setup. Using a physics-based material model for polyurea, the test was numerically modeled in LS-DYNA and verified by comparing to experimental results.
