ABSTRACT
Microstructural and computer simulation studies have been carried out on Cu, Fe, and Ta Explosively Formed Penetrators (EFPs) in an effort to relate the computer simulated yield stress contour maps with the measured microhardness maps along EFP longitudinal half-sections, and to perform microstructural validations of the hydrocode. Preliminary simulation work is presented here along with prominent microstructural features in order to highlight the issues that may be of considerable significance in future EFP research.
