Elastic Green’s function for a composite solid containing a crack at an angle to the interface
We describe the virtual force method of calculating the elastic Green’s function for a bimaterial composite solid containing a planar interface and a semi-infinite crack inclined at an arbitrary angle to the interface. The crack tip is assumed to be at the interface and extends to infinity. The calculated Green’s function satisfies the condition of the continuity of tractions and displacements across the interface and the zero traction boundary condition at the surfaces of the crack.
