文摘

A new critical plane-based mixed-mode delamination failure criterion is proposed in this study. First, many existing models are reviewed and their capability to handle the mixed-mode fracture of general anisotropic materials are discussed. Following this, a previously developed critical plane approach is extended to analyze the interfacial fracture of composite materials by considering the anisotropic fracture resistance under mixed-mode loadings. Next, comparison with extensive experimental data available in the literature is performed to demonstrate the validity of the proposed criterion. A general good agreement is observed between the model's predictions and experimental observations. Finally, some conclusions and future work are drawn based on the proposed study.
