平方律屈服准则

Square Law of Yield Criteria

本文提出了在复杂应力状态下各向同性材料的屈服机理及其平方律的数学结构,建立了包括三种广义屈服准则的一个体系。该体系包容了经典的屈服准则及其重要的修正理论,以及近期发展的新理论。

In this paper the yield mechanism and its mathematical structure are made for isotropic materials under complex stress state, and a system of yield criteria is set up which consists of three generalized yield criteria. It contains classical yield criteria,their important modified theories and some new theories of late.
