摘要
从材料的滑移应力与静水应力的相互作用，阐明了各向同性材料在复杂应力状态下的三种弹性破坏现象。剪切屈服、脆性断裂和塑性体积屈服，并以两个极限应力准则完整地表述。作为一个例子，以平方主剪应力屈服准则为基础，构造了广义平方主剪应力准则方程组，理论结果与一些岩土类材料的实验数据相吻合。
hree kinds of elastic failure of isotropic materials under the complex stress state: shear yield,brittle fracture and ductile volumetic yield, are explained from the viewpoint of the interation between slipping stress and hydrostatic stress, and expressed by two limit criteria of stress. As an example, two limit criteria of generalized square principal stress are proposed. The result shows a satisfactory agreement with some experimental data of rock and soil materials.
