## A finite element based crack-closure integral for determining strain energy release rates for two-dimensional elastostatic and elastodynamic crack problems in finite bodies is evaluated. Both the J-integral and crack-closure integral are used to obtain strain energy release rates from the finit
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
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
