Elastic-plastic analysis of crack in adhesive joint by combination of boundary element and finite element methods

This paper concerns with a combination method of the boundary element method and the finite element method for elastic-plastic analyses. The combination method proposed here is based on the substructure method using the conjugate gradient method. This combination method has the advantage of saving CPU time and memory storage size over the finite element method. The combination method is applied to a J-integral analysis of a crack in an adhesive joint. The effect of bond thickness on the J-integral is discussed.
