摘要
本文从最小势能原理出发,导出了具有裂缝的弹塑性各向异性损伤介质的守恒积分方程.并针对二维问题定义了损伤材料的J积分.为实现结构分析中损伤和断裂力学的结合做了初步的探讨。
In this paper, the conservation integral equations in an elasto-plastic anisotropic damage medium are established by the use of minimun potential energy principle, then the J- integral for damage material is also discussed. This J-integral is applicable to the combining of damage mechanics and fracture mechanics.
