Damage Finite Element Analysis of Nano-Composite Ceramics
Based on the experiments, micro-mechanics and finite element theory, nano-composite 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. Then we use ANSYS program to construct the cell model and simulate the tensile stress field of it. Then the stress distribution and the material properties are analyzed. 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. At last the stress change and damage evolution route are simulated when the damage happens using the element birth and death technology. The work of the paper is accordance with experiments and theories.
