Recently integral large composite structures have been applied to many structures of vehicles because of their low cost and high reliability. However, since the structures are large and complicated, a fracture simulation system is required to assess the safety of inspected damages. In this study, the efficiency of a 2-dimensional FEM damage simulation for splitting, matrix cracking and nonlinear share deformation was examined as compared with the experimental results. To improve the analytical results, a fractal distribution model and a share bridging effect model were constructed based on the fracture micro-mechanisms of matrix cracking and splitting, and a damage simulation based on the models was developed. As a result, a simulation that considered the fracture micro-mechanism was found to be effective for damage estimation of FRP laminates.
