摘要

A systematic and comprehensive assessment of popular 3D macroscopic failure criteria for predicting pure inter-fiber fracture of transversely isotropic unidirectional (UD) composites is performed in the present study. The maximum stress/strain, Tsai-Hill, Hoffman, Tsai-Wu, as well as the Christensen, Hashin, Puck, and LaRC05 criteria for the inter-fiber fracture (IFF) mode, are briefly reviewed. The theoretical foundations of each criterion are critically examined at first. Afterwards, comparisons between the failure criteria which have passed the theoretical examination and the experimental data available in the literature are conducted. The results indicate that the action-plane based criteria perform best in qualitative description of the failure responses, yet no criterion is able to accurately predict the failure stresses in all loading conditions. Even under the same combined stress state, the performance ranking varies for different material types. The main advantages and shortcomings of the evaluated criteria are identified and summarized using this combined theoretical and experimental analysis approach.
