摘要
基于广义双剪应力强度理论 ,创建了一种新的三维复合型断裂准则——广义双剪断裂准则。研究结果表明 ,该准则与一些试验结果吻合很好 ,它不仅可以广泛地用于分析岩土类材料的复合型断裂问题 ,而且也可以用于金属材料的断裂分析。因此 。
A new criterion of three dimensional mixed mode cracking is developed based on the generalized twin shear strength theory. The consistence of the criterion with the test results indicates the criterion is suitable for analyzing mixed mode cracking not only of rock and soil but of metal as well.
