从Eshelby理论出发，采用Eshelby等效包容体法，结合Mori-Tanaka平均场方法，将微孔洞考虑成不同于基体和包容体的第三相，建立了双相合金的含损伤本构框架。将钨和粘结相的热粘塑性本构方程代入后，得到了钨合金含损伤本构方程，并将其编入一维Lagrange差分程序进行模拟，模拟结果与实验吻合得较好。

Based on Eshelby's theory and considering the micro-voids inside the tungsten alloy as the third phase, a constitutive frame involving damage factor was constructed by means of Eshelby's model of equivalent inclusions and Mori-Tanaka uniform-field method. Then, introducing the constitutive relationship of tungsten grain and matrix into the above frame, as a result, the constitutive equation involving damage factor of tungsten alloy is obtained. By use of a one-dimensional finite-differential Lagrange program, the numerical computing of the spalling phenomena of tungsten alloy was made and the agreement of the computing results with the experimental data is pretty well.
