Abstract
As part of a study of the crack arrest capabilities of tough steels[1], efforts are underway to simulate rapid crack extension and arrest in elastic-plastic finite element models. As a first step, stationary cracks in compact tension specimens have been modelled and the effects of loading rate, strain rate sensitivity and inertia on JI have been examined. The aim of this work is to examine those features of the plastic zone influential in determining the toughness, namely, the size of the process zone, and the crack tip opening displacement.
