A compact shear fracture specimen has been proposed for the study of the edge sliding mode, Mode II, of crack propagation. The purpose of this investigation was to numerically determine the effect that crack length, specimen geometry, and applied load, has on the Mode II stress intensity factors for this specimen. Numerical results were compared to those obtained independently by another investigator using boundary collocation and photoelastic techniques. In addition, the initial angle of propagation was numerically determined for selected specimen configurations and crack lengths. The Mode II stress intensity factors were generated by using displacement and strain energy release rate methods. The initial angle of propagation was obtained by the strain energy density technique.
