Abstract

This paper provides simulations of ductile crack growth in test specimens using an element-size dependent damage model. The present method used in this paper is based on a stress modified fracture strain damage model with a stress reduction technique. The calibrated damage model is used to predict the load versus ductile crack growth response of test specimens. These tests included some samples that contained self-balancing residual stress distributions. The influence of a residual stress on the load versus crack growth relationship is accurately simulated using the element-size dependent damage model.
