In an accidental explosion of ammunition magazine, concrete debris throw hazard is a major safety concern. The current approach to collect explosively-damaged debris after test does not yield representative test data on debris launch condition. This research is initiated to study the possibilities of using polymeric foam material to soft-catch concrete debris, without inducing additional damage. Preliminary design of the soft-catcher are first performed using a modified analytical shock wave model. Numerical analyses using LS-DYNA are subsequently carried out to verify the analytical model assumptions and account the effect of rigid end backing of the soft-catcher. Following then, the debris penetration problem is escalated into 2-D space domain, in order to include the influence of tearing resistances within the soft-catcher. The observed phenomena are eventually translated into design parameters for the soft-catcher.
