Abstract: The study of problems of bimaterial interface and interface fracture is one of the centralissues of solid mechanics at present. Boundary element method is increasingly manifested to bean effective numerical approach to the study. So an elastoplastic boundary element method withbimaterial fundamental solution, Dundurs-Hetenyi solution, was first proposed by the first authorand is developed in this paper by consideration of the structural features of bimaterial. Becausethe interface conditions of bimaterial a...
