✦ Synopsis

Stresses around an interface crack in an elastic layer sandwiched between two elastic half-planes are determined. The crack surfaces are loaded by an equal and opposite normal stress. It is assumed that no contacting regions exist near the crack tips. Application of the Fourier transform technique reduces the problem to that of solving a pair of dual integral equations.

To solve the integral equations, the crack surface displacements are expanded in trigonometrical functions accompanied with the unknown coefficients.

To solve these unknowns, the Schmidt method is used. The stress intensity factors are calculated numerically for some combinations of Young's modulus ratio of the composite materials and the crack length.
