In the present paper, the progressive damage modeling of a composite layup laminate is studied. The shell elements are used to include property degredation of the composite plies of composite layup. The Maximum Stress and Tsai-Wu stress-based criteria for in-plane failure are used to predict the first ply failure (FPF) force and Hashin criteria for predicting the progressive damage. The analytical results obtained in MATLAB are in a good agreement with the numerical results obtained from numerical model and ABAQUS-CAE.
