The energy release rate G for 2‐D rubbery material problems with non‐conservative crack surface tractions is calculated by a modified version of virtual crack extension method with finite element solutions. The formulation is demonstrated to be ‘patch‐independent’ and therefore a complicated finite element model around the crack tip is not required.
