In this study, a method for FE analysis of woven angle ply laminates has been proposed. It is important to characterize the effect of laminate angle of woven fabrics on the mechanical behaviors because woven angle ply laminates has been widely used as quasi-isotropic material in many fields. Though FE analysis of on-axis woven fabric composite has been able to carry out, FE analysis of woven angle ply laminates has been difficult for its complicated non-periodic structure. As the method to

We have generated FE model of homogenized off-axis woven fabric laminate as the global model, matrix as meso model, and fiber bundles as local model. By using this method, woven fabric laminates with arbitrary laminate angle can be analyzed considering the effect of lamination of woven fabrics on the strains in the fiber bundles. The accuracy of the method has been verified when using 64 Gaussian points for integrations.
