Chen, E P

Perforation of aluminum plates by steel penetrators is the subject of discussion in the present investigation. Specifically, laboratory scale experiments were simulated using the transient dynamic finite element code PRONTO 2D. For the range of impact velocities considered in this study, the penetrator experiences little deformation while the target exhibits ductile hole-growth behavior. Thus, both the penetrator and the target are taken as elastic/plastic hardening materials in the finite element model. Detailed numerical treatement of the perforation process is discussed. Comparison between calculated results and experimental data show good agreements. 6 refs., 8 figs., 3 tabs.
