Abstract: This paper seeks to develop and validate a methodology for predicting the failure of woven composite laminates. A material model and user-subroutine were created for woven composites, which were then used to carry out finite element analyses (FEA) for woven composite laminates. Forty coupon laminates made from T650/5320 graphite-epoxy material system were notched and tested under tensile loading conditions. Data was recorded using strain gages and digital image correlation (DIC). Portions of the test data were used to define the material model more completely and the rest of the test data was used for validation. The model predicted the failure load of more than half of the test cases within 5%, which indicates that the model performs well for the range of coupons tested and the intended application of the model.
