The strain energy density factor or .S-criterion [l] has been widely used in fracture mechanics and our work confnms that it can be used to explain the cracking behavior of a homogeneous, isotropic solid. However, it was found to be inadequate for some composite materials and a new hypothesis called
## W-In this paper, the efht of couple-stresses on the strain energy release rate for an interface crack is examined. An internal pressure is applied on surfaces of the crack situated between two dissimilar half-planes. The oscillatory stress singularities and material overlappings usually appear
