Elastic fracture mechanics analysis of bi-materials using boundary element method

An analysis of an elliptical hole inclusion between the two materials is done, along with the relation between an interface crack in between two isotropic elastic half palates that are dissimilar. Only tensile loads operating perpendicular to the crack axis and acting on the matrix are considered. F...
