Abstract

A two-dimensional explicit finite difference (EFD) computer program is used to simulate three large-deformation dynamic tests: the Charpy V-notch impact toughness test, oblique impact of a cylindrical rod on armor plate, and driving of copper liners by a shaped high-explosive charge. The relationship of the EFD formulation to the more recently developed explicit finite element (EFE) formulation is discussed.
