Abstract: Examines the elastic field of a semi-infinite wedge crack and its interaction with a screw dislocation under mode III loading conditions. Expression of the stress field around the wedge crack; Relationship between the stress intensity factors for the wedge and sharp cracks; Calculation of the crack extension force for the wedge crack.
