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.
