Stresses around a crack in an interfacial layer between two dissimilar elastic half-planes are obtained. The material constants of the layer vary continuously within a range from those of the upper half-plane to those of the lower half-plane. An internal gas pressure is applied to the surfaces of the crack. To solve the problem, the interfacial layer is divided into several layers with different material properties. The boundary conditions are reduced to dual integral equations. The equations are solved by expanding the differences of the crack faces in a series. The unknown coefficients are determined using the Schmidt method. Numerical calculations are carried out for some crack configurations.
