Thermal stresses around a crack in the nonhomogeneous interfacial layer between two dissimilar elastic half-planes

Abstract

Thermal stresses around a crack in the interfacial layer between two dissimilar elastic half-planes are solved. The surfaces of the crack are assumed to be insulated. The material constants of the interfacial layer are assumed to vary continuously from those of the upper half-plane to those of the lower half-plane. Uniform heat flows perpendicular the crack. Stress intensity factors are calculated numerically for several thicknesses of the interfacial layer.
