Based on experiments, micro-mechanics and finite element theory, nanocomposite ceramics is simplified as representative volume cell in the paper, and in order to study the interaction of the particles, each cell concludes two nano-ceramic particles. We use ANSYS program to construct the cell model and simulate the stress field. The stress distribution and the material properties are obtained. The results show that the stress is uneven in the cell and the elements near the nano-ceramic particle with high stiffness will damage first. Finely, the stress change and damage evolution route are simulated by using the element birth and death technology. The computational results are accordance with experiments and theories.
