## Abstract Griffith's fracture criterion describes in a quasistatic setting whether or not a preβexisting crack in an elastic body is stationary for given external forces. In terms of the energy release rate (ERR), which is the derivative of the deformation energy of the body with respect to a vir
The strain energy release rate for a crack at the interface of dissimilar isotropic materials was derived from an existing crack tip field. In the derivation, the J-integral along a special near tip contour was used. A single expression of the strain energy release rate corresponding to different de
## 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
The strain energy release rate for a straight-fronted edge crack in a bar of circular cross section subjected to pure bending is determined. The cracked bar is modelled with two-dimensional plane-stress finite elements and strain energy release rates, determined from this model, are shown to be in c
