广义非线性强度理论体系

广义非线性强度理论用一个表达式统一描述各种材料在 平面及子午面上的非线性强度特性，形成了一个全新的非线性强度理论系统，使非线性强度理论从适用于某一类特定材料的单一非线性强度理论发展到可以适用于众多不同材料的广义非线性强度理论，完善了强度理论体系。广义非线性强度理论包含了一系列现有的和可能有的单一非线性强度理论，如Mises准则、SMP准则等。利用土、岩石和混凝土强度试验结果验证了广义非线性强度理论适用于多种材料的优越性。

System of generalized nonlinear strength theory

A unified expression describing the nonlinear characteristics of strengths of various materials on the π plane and the meridian plane is used in the generalized nonlinear strength theory. Thus a brand new system of the nonlinear strength theory is formed. The nonlinear strength theory is developed from the single nonlinear strength theory which can be just suitable to a certain material to the generalized nonlinear strength theory which can be suitable to various materials. Therefore, the system of strength theory is completed. The generalized nonlinear strength theory includes a series of the single nonlinear strength theories which have already existed and might appear in the future, such as Mises's criterion, SMP criterion, etc.. The superiority of the system of the generalized nonlinear strength which is suitable to various of materials is verified by the strength tests on clay, rock and concrete.
