Stress intensity factors are important parameters affecting stress strain behavior in the vicinity of a crack tip. They are used for the strength evaluation of machines, structures, and various machine elements. In fracture problems, stress intensity factors obtained theoretically and experimentally have been effectively utilized in the analytical evaluation of the effect of cracks. The effect of surface crack of a cylindrical and a hollow cylindrical bar and an inclined crack of a hollow cylinder subjected to torsion. In this study, stress intensity factor K_<III> of mode III which expresses the stress state in the neighborhood of a crack tip is used. Stress analysis was conducted on the inside of a hollow cylinder in the axial direction of a three-dimensional crack tip subjected to torsion by combining the caustic method and the stress freezing method.
