耦合热弹塑性损伤介质的守恒积分

Conservative Integral in Coupled Thermoelastoplastic Damage Medium

本文首先提出小变形耦合热弹塑性损伤问题的一个自由能形式的变分原理。然后利用该变分原理导出了一组守恒积分方程并定义了守恒积分。

In this paper, a variational principle of free energy form in coupled thermoelastoplastie damage medium is presented and proved at first, then a group of conservative integral equations are derived from the principle and a pathindependent integral is defined for 2-D problem.
