A model is constructed to evaluate the mode II stress intensity factor (SIF) for the layered material with a center crack under an arbitrary shear crack surface loading. The mixed boundary value problem is formulated by the Fourier integral transform method and a Fredholm integral equation is derive
The stress intensity factor at the deepest point of a semi-elliptical surface crack is calculated for stress gradients in direction of depth. The method is based on weight functions. The crack opening displacement for the reference problem is calculated with a method proposed by Petroski and Achenba
