摘要：
A contribution is given to the theoretical research on the stiffness of ceramic materials, under the approximation of the average stress field, the relation E = E-o(1-p)/(1 + 2.5p) is derived to describe the dependence of the modulus of elasticity on porosity. The prediction of this model is consistent with the experimental data from several ceramics such as reacting sintered Si3N4, MgO and MgAl2O3.
