Abstract

We have performed continuum simulations of ejecta production from multiply-shocked metal surfaces. We describe the underlying computational capability, and discuss the results of our calculations. While still at a developmental stage, these results demonstrate the fundamental linkage between the production of ejecta and sub-surface material failure, explaining qualitative features seen in previous experimental results.
