内容説明
This title provides an elastoplastic formulation for the analysis of problems in nonlinear fracture mechanics. The method relies on the use of two independent boundary integral equations - the elastoplastic boundary element method (EPDBEM). The two equations of the method are the displacement equation on one face of the crack and the traction equation on the opposite face. This feature allows for the analysis of general mixed-mode crack problems within a single-region formulation.
