Numerical Analysis of Stable Crack Growth in Elastic-Plastic Materials in Small Scale and General Yielding
Abstract
dc:descriptionStable crack growth problems in elastic-plastic materials are investigated with the aid of the finite element method. The formulation used for steady state crack growth under small scale yielding conditions has the feature that the finite element mesh convects along with the moving crack tip. Various models for plastic flow were used. In Mode III, calculations were carried out for J(,2) incremental theory and a modified J(,2) deformation theory meant to introduce effects related to flow at a yield surface vertex.
