| Abstract: | Some theories of fracture mechanics concerning crack study theory are applied to the research of high-speed shearing. Based on the theory of strain energy density factor, the law of crack growth and the mechanism for improving section quality in high-speed shearing are analyzed. And then, the regular high-speed shearing law and the crack growth path under regular high-speed. Shearing condition are also presented in this paper. |
