Abstract
In this paper, we deal with the application of Godunov’s method for the computational modeling of dynamic fracture. First the numerical scheme is presented. The material is assumed to obey Hooke’s law in the elastic region, and to have a linearly workhardening behaviour in the plastic region with the von Mises yielding condition. Three numerical examples are presented to demonstrate the capability of the method, and to show the time history of forthcoming plastic zones and their growing size in a plate with a crack or a rectangular hole when the plate is loaded by a given dilatational pulse. Varied parameters are the work-hardening parameter and the strength of the loading pulse
