Prediction of delamination front’s advancement direction in the CFRP laminates with mechanical couplings subjected to different fracture toughness tests

The paper deals with formulation of an analytical tool for predicting the direction of interlaminar crack propagation in the CFRP composites with mechanical couplings. It is a consecutive work in the study and covers analysis of the typical fracture toughness tests (DCB, ENF and ELS) applied to fiber-reinforced composites with general ply configurations. The results of the VCCT calculations of delamination onset and propagation performed in the...
