Abstract
In this paper the elastoplastic dual boundary element method (EPDBEM) is presented for the analysis of elastoplastic fracture mechanics (EPFM) problems. The dual equations of the method are the displacement and the traction boundary integral equations. The use of these dual equations allows the solution of general mixed-mode crack problems with a single-region formulation. The elastoplastic behaviour is modelled through the use of an approximation for the plastic component of the strain tensor on the region expected to yield. This region is discretized with internal quadratic, quadrilateral and/or triangular cells. The possibility of crac
