The Damage Evolution Analysis of Fiber-Eutectic

Based on micro-mechanics and finite element theory, the stress field of fiber-eutectic was researched by using the ANSYS program. First, in order to study the interaction of fiber and interphase, fiber- eutectic can be simplified as representative volume cell. 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 interphase 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.
