ELASTIC GREENS-FUNCTION FOR A DAMAGED INTERFACE IN ANISOTROPIC MATERIALS

We present the derivation of the elastic Green's function for an aniso tropic bimaterial in a state of plane strain, A Fourier transform meth od is used to calculate the Green's function. A discontinuity in displ acement is permitted across the interface between the two solids. This provides a useful functional form for parameterizing damage along an interface. We show several examples for the form of the displacement d iscontinuity and calculate the displacement Green's function for each. The Green's function derived here is applicable to a variety of inter face problems between two different anisotropic solids or for two simi lar solids at different orientations.
