By using the finite element technique, stress intensity factors have been obtained for finite rectangular plates and the results have been given for various h / a , W / a and L / W ratios. By using a three‐dimensional isoparametric element, the problem has been considered as a three‐dimensional one and the variation of stress intensity factor across the plate thickness has been found to be nonlinear.
