New Sliding Surface Techniques Enable the Simulation of Target Plugging Failure

Abstract

Techniques were developed and incorporated into EPIC-2, a Lagrangian finite element impact code, to accomplish the dynamic relocation of sliding surfaces. This development was necessary in order to model ballistic impact situations involving deep penetration and/or perforation of targets. These techniques were first applied to the modeling of axisymmetric ballistic impact situations involving kinetic energy penetrators versus targets which failed by plugging due to high strains. The development of the criteria required for target failure to begin and proceed naturally is included.
