This article focuses on understanding the progressive failure behavior and predicting the failure strength of the E-glass/epoxy-woven composites. Two types of the plain weave composite material are investigated. A homogenized woven composite model is developed to obtain the properties of these materials based on micromechanics. Failure criteria are embedded into this model simultaneously and the material properties are degraded and updated when damage occurs. The model is incorporated into a finite element code, ABAQUS, via a user-defined material subroutine. Using this model, the progressive failure behavior can be easily traced and the predicted stress–strain curves and failure strength show good accuracy compared with the experimental results.
