The classic plastic constitutive relation, multi-yield surface constitutive relation and over-stress viscoplastic constitutive relation are a special example of this constitutive relation.

经典塑性本构关系、多屈服面本构关系及过应力型粘塑性本构关系只是本文的特例。

Giving an imitation of traditional plastic theory , a damage surface model on brittle rock about temperature in stress-space is introduced and the evolutionary law is discussed qualitatively.

参照经典塑性力学的屈服面理论，引入了温度作用下应力空间中脆性岩石的损伤面模型，定性地讨论了荷载和温度影响下损伤面时的演化规律。

Endochronic plasticity based on non-yield surface is deduced into the displacement-based finite element method and the plastic strain direct method is proposed for the plane stress problem.
