A new four-parameter equivalent strain for isotropy damage model is presented.

提出了一种新的用于各向同性损伤模型的四参数等效应变。

The stress and strain of materials have mostly been analysed in planar isotropy.

迄今有关材料应力和应变状态的分析多限于面内同性材料。

The theory of isotropy damage is based on the hypothesis that the material and damage are symmetrical and isotropic.

各向同性损伤理论是建立在材料是均匀的、各向同性的以及损伤也是各向同性的假设基础之上。
