The method for the additionaldeformation of the bar with initial stress was modified, by using a second-order deformation theory.
第八章讨论了上述理论的应用范围,提出了用二阶理论改进的方法。
2
Yield function is introduced to describe the plastic deformation and a new damage function is proposed to describe the additionaldeformation due to the damage of soil structure.
塑性变形常用屈服函数描述,损伤变形则引入一种类似的损伤函数加以描述。

Usually yield function is introduced to describe the plastic deformation, however, a new damage function is proposed here to describe the additionaldeformation due to the damage of soil structure.
