Modeling Adiabatic Shear

Abstract

This paper discusses the techniques and criteria developed to simulate target plugging due to adiabatic shear and presents simulations of two impacts involving steel rods against titanium alloy targets. A Lagrangian dynamic impact code, EPIC-2, was used as the basis for this effort. A stress/ (strain, strain rate, temperature) relationship in which temperature was based on the conversion of plastic work into heat, was used for the target material; newly developed sliding surface techniques, combined with an adiabatic slip criterion, controlled target failure. Results indicate that such techniques show considerable promise in modeling this complex phenomenon.
