Abstract

Our aim was to achieve a basic understanding of the vessel investigations under cyclic deformations and to validate ductile fracture mechanics concepts concerned with the cyclic J-integral. Several three-dimensional finite element analyses have been performed for components subjected to cyclic plastic deformations. Based on the slightly modified virtual crack extension method, cyclic J-integral values were computed and have been discussed. As long as the material plasticity around the crack tip is confined, the J-integral method is applicable and appears to be a suitable parameter for handling low-cycle fatigue problems.
