| Abstract: | Eshelby's epuivalent inclusion method and a three-phase mean-field micromechanical model are applied to evaluating the thermomechanical properties of the ceramic-metal gradient material.The thermal stness generated during cooling from sintering temperature is analyzed by finite element method. According to the numerical results for constituent distribution,a MgO/Ni FGM with thermal stress relaxation has been obtained. |
