Woven composites have been used in many fields such as cars and ships, etc. However, it is very difficult to evaluate the mechanical behavior and the strength because of the complicated geometrical shape. In order to solve the difficulty, we have developed a numerical multi-scale simulation program based on damage mechanics. The following points are the keys to simulate the mechanical behavior; (1) The generation technique of FE model with yarns and matrix, (2) The classification of anisotropic damage mode based on damage mechanics, (3) Multi-scale modeling by Mesh superposition method. In this paper, the numerical technique is described, and the damage development for woven GFRP laminate based on multi-scale analysis of M method has been estimated.
