| Abstract: | An inverse problem in fracture mechanics related to the stress shearing is discussed. The crack growth path under the condition of stress shearing and the relations between the axial gap and the crack growth path are analsed based on the inverse problem,and then, the regular shearing law and the preloading method of stress shearing are also preseted. |
