EPIC-2 Calculated Impact Loading History for Finite Element Analysis of Ballistic Shock

Abstract

Although the EPIC-2 code can predict the ballistic shock environments in projectile-impacted targets, these targets must be axisymmetric. By modifying the code one can calculate the target loading history which can be used as input for a finite element analysis of the ballistic shock in normal impacted, non- axisymmetric targets. The loading history of a 20 mm fragment simulator projectile with an impact velocity of 1508 m/s on a 914 mm x 70 mm thick circular rolled homogeneous armor plate has been calculated by the EPIC-2 code and has been used in an ADINA finite element analysis of the plate. Comparisons of the EPIC-2 and ADINA response calculations show that the EPIC-2 calculated loading history can be used as loading input for finite element ballistic shock analysis.
