Damage analysis of open-hole compression laminates

A model for the damage analysis of the open-hole compression composite laminates was developed. The model divided the failure modes of composite laminates into intra-laminar and inter-laminar damage. The failure modes and failure loads of different laminates were predicted and compared with the experimental results based on progressive failure analysis methodology. The results show that the model can simulate damage initiation, damage progression, final damage and predicted failure mode and failure load of laminates with central circular holes subjected to compression load, then predict the failure mode and failure load of open-hole compression laminates.
