PARTIALLY BONDED BIMATERIAL PLANE UNDER TENSION

A bimaterial problem is considered for shapes that are symmetrical with respect to an interface that is finite and straight. A rational mapping function and complex stress functions are used to obtain a general solution for bonded halfplanes with cracks at an end of the interface. A stress analysis is carried out for a state of uniform tension at infinity, which is either symmetrical or antisymmetrical with respect to the interface. Stress distributions and stress-intensity factors are obtained for various crack length and elastic constants. When one material is in tension and the other is free from traction, stress-intensity factors are also investigated. The bond effects on the stress-intensity factors are studied. The elastic constant's effects on the stress-intensity factor for a short crack and the stress function for special material constants are also investigated. © ASCE.
