【摘要】 Griffith理论用于复合型断裂已被许多人研究过。本文的工作是在能量释放率理论的基础上,通过计算任意方向上的能量释放率,推导出最大能量释放率准则的一般表达式,並将它同Ⅱ—Ⅲ和Ⅰ—Ⅱ—Ⅲ复合型断裂实验进行了比较。更多还原

【Abstract】 Griffith’s theory applied to mixed mode fracture had been studied by many people. The eontribution of this paper is that, on the base of energy release rate erite-rion, ealculat ing the energy release rate at arbitrary direction, the general form of energy release rate eriterion has been derived and compared with measured results of fraeture testing under Combined Mode Ⅱ-Ⅲ and Mode Ⅰ-Ⅱ-Ⅲ loading.更多还原
