## Ab&aet -A simple representation for the crack-face disp~cement is emptoyed to compute a weight function soiely from stress intensity factors for a reference loading con~tion. Crack face disputants given by the represe&&n are shown to be in good agreement with analytical resub for cracked tensil
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
A procedure is developed for determining the stress intensity factors in cracked polygonal plates. The method uses eigenfunctions of angular regions and satisfies the boundary conditions exactly. Westergaard's stress functions are used to satisfy the boundary conditions at the crack. Numerical resul
