A numerical technique for simple and efficient integration of weight functions is presented. The method enables the stress intensity factors to be calculated with the aid of a hand calculator for any non-linear stress distribution normal to the crack surfaces. The proposed integration routine is val

For the application of the weight function method the crack opening displacements for a reference case have to be known. An approximate method to derive the crack opening field from the stress intensity factor was proposed by Petroski and Achenbach [Engng Fracture Me&. 10,257 (1978)J. The limited ac
