| Abstract: | 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. |
