摘要
将ｌｅｍａｔｉｒｅ应变等价假设应用于岩石材料的纯剪切情况，推导了相应的损伤变量Ｄ和应变能释放率Ｙ的表达式；以损伤应变能释放率为基础，探讨了各向同性岩石在不同受力状态下损伤变量间的关系。
he lematire's strain equivalent hypothesis is applied to pure shear of rock material .the corresponding formulas of damage variables D and strain energy release rate Y are devived,and on the basis of the strain energy release rate, the relationship of different variables of is tropic rock under different loaded condition are discussed.
