Abstract
A two-dimensional elastic-plastic finite element analysis of a single edge cracked specimen is performed to investigate the constraint effect on the initiation of ductile fracture. Shallow and deep cracks are considered, and a lateral tensile or compressive constraint is imposed on the specimen by assuming the generalized plane strain condition. The Gurson's constitutive equation for porous plastic material is employed to take into account the nucleation and growth of microvoids and the element vanish technique is used to model the initiation of ductile fracture. It is shown that the J-integral at fracture growth initiation varies significantly depending on the crack length and the state of lateral constraint. We also discuss the usefulness of the two parameter J-Q theory which defines the fracture initiation under various constraint conditions.
