The Modelling of High Strain Rate Deformation and Penetration Problems Using Finite Element Analysis

Abstract

This paper compares the experimental results of high strain rate deformation and target penetration studies of an explosively formed projectile (EFP) warhead design with the values predicted using a finite element analysis (FEA) modelling technique. Utilisation of experimentally determined high strain rate ( up to 9000/s ) materials properties in the FEA prediction of EFP liner formation and target penetration simulation showed good agreement with the experimentally determined results.
