势面 meaning in Chinese

potential surface

Multi - potential discontinuous bifurcation model for localization of jointed rocks
裂隙岩体局部化破坏分析的多重势面分岔模型
This paper uses the method of tensor to proof the tenable condition of generalized plastic potential , discuss the mathematical essential of the associated and disassociated flow rule and the relation of the yield surface and plastic potential surface , reason the expression of plastic factor strictly . debate the limitation on drucker ' s postulate . subsequently , this paper gives the mathematical basis of constitutive theory involving the rotation of principal stress axes . so it is proved that the mathematical and mechanical foundation of the generalized plastic mechanic
本文运用张量的方法论证了广义塑性位势理论成立的充要条件，讨论了关联与非关联流到法则的数学实质，屈服面与塑性势面的关系，严密推导了塑性因子的表达式，讨论了drucker公设的局限性，并给出了考虑主应力轴旋转时土体本构模型理论的数学依据，系统的论证了广义塑性力学成立的数学力学基础。
