摘要：
Fatigue damage of fibre-reinforced polymers is of interest to researchers and designers. In this paper new direct computational method was developed in order to reduce computational costs for life prediction of composites. Constitutive model is based-on plasticity and damage mechanics. Macro-micro transition stress concentration tensor has been used in order to take into account influence of the micro-structure. Plasticity yield surface is based-on the modified Raghava criterion. Damage of matrix and transverse cracking are governed by quadratic damage surface. Method was examined on a fibre-reinforced polymer composite plate with unidirectional plies.
