Boundary element analysis of fracture mechanics in anisotropy bimatierials

摘要

This paper presents a boundary element formation for the analysis of linear elastic fracut re mechanics problems involving anisotropy bimaterials. The most important feature associated with the present formulation is that it is a single domain method, and yet it is accurate, efficient and versatile. In this formulation, the displacement integral equation is collocated o the uncorked boundary only, and the traction integral equation is collocated on one side of the crack surface only. The complete Green's functions for anisotropy bimaterials are also interfacial crack part. A special crack-tip element is introduced to capture exactly the crack-tip behavior.
