Abstract:

A series of numerical simulations of ground response to a high- explosive detonation was used to examine the influence of material models on calculated central-peak formation in shock-produced craters. One simulation of the 20-ton high-explosive detonation Mixed Company II showed that computed motions at 16.4 msec. when ballistically extrapolated, were consistent with the observed crater and formation of a central mound. Compaction, layering, and material yield models were varied in additional simulations. The results indicated the occurrence of a central mound is primarily dependent on material properties of the medium.
