Frictional interface crack in anisotropic bimaterial under combined shear and compression

The problem of a frictionally sliding interface crack embedded in an anisotropic bimaterial is investigated. Under remote normal compressive and shear load the crack faces are treated as completely closed in the direction of the normal load while in other directions the crack faces are allowed to slide. The frictional coefficient over the sliding zone is assumed to be constant. A set of singular integral equations is formulated which is valid for general anisotropic bimaterial. The nature of singularities for frictionally sliding bimaterial is investigated. It is found that for general anisotropic bimaterial the problem may be treated as a homogeneous anisotropy as long as and hence the stresses developed on the frictional surface would be uniform for such bimaterial. If is not identically zero but with ...and with the surface being frictionless then the stresses over the crack faces are square root singular. The homogeneous anisotropy satisfying ...would transmit the load freely across the crack faces without any interference. For monoclinic bimaterial, the orders of singularities are found to depend on the material constant )lambda)and the frictional coefficient f and are either of order (delta)or 1?(delta) depending on the direction of the frictional force. The stresses on the interface for monoclinic bimaterial are also given explicitly.
