Elastic green's function for a bimaterial composite slid containing a crack inclined to the interface

摘要

An analytical closed-form expression is derived for the elastic Green's function of a bimaterial composite solid con- taining a planar interface and a straight crack inclined at an arbitrary angle with the interface. The crack tip is assumed to be at the interface. Both the constituent materials of the compo- site are assumed to anisotropic. The Green's function satisfies the interfacial boundary conditions of continuous tractions and displacements, and zero tractions at the crack surfaces. The boundary conditions are satisfied by using the virtual force technique.
