In this paper Mode II stress intensity factors for radial internal and radial internal edge cracks in a circular ring or a hollow cylinder subjected to uniform crack surface shear stress are obtained by using the singular integral equation techniques. First, solutions for a circular ring or a hollow cylinder with an embedded edge dislocation (bx, 0, 0) are obtained by complex variable method and superposition technique. Integrating the dislocation solution along the crack, we get a singular integral equation to be solved numerically. Numerical examples are given, for various crack geometries and radius ratios. The numerical results are obtained for a uniform crack surface shear stress tau0.
