Abstract
Weight functions are developed for determining stress intensity factors of cracks along an interface between two linear, elastic materials. As a result of the interface, both mode I and II components will be present for all but very special loading cases. The weight functions are employed to produce exactly the known stress intensity factors of a crack along an interface loaded by tensile and shear point forces.
