摘要：

Based on micro-mechanics and finite element theory, the stress field of Ni base alloy ceramic composite was researched by using the ANSYS program. First, in order to study the interaction of the particles, Ni base alloy ceramic composite can be simplified as representative volume cell. Each cell concludes two ceramic particles. Then we use ANSYS program to construct the cell model and simulate the tensile stress field. The results show that the stress is uneven in the cell and the elements near the particles with high stiffness will damage first. At last the stress change and damage evolution route are simulated by using the element birth and death technology. The computational results were accordance with experiments and theories.
