Recently, applications of integrated large composite structures have been attempted to many structures of vehicles. In order to improve the cost performance and reliability, it is necessary to judge the structural integrity of the composite structures. Fracture simulation techniques using FEM have been developed for the purpose. Influence of the element size on damage growth process is well know but appropriate element size to obtain more accurate results and less calculation time is not investigated in detail. In this study, analytical damage growth process and load-displacement relationship are compared with experimental ones for various mesh sizes. As a result, it is shown that the appropriate mesh division is required for the fracture simulation.
