Finite element analysis of fatigue crack growth in CFRP-repaired four-point bend specimens

•CFRP repair can effectively enhance the fatigue life of edge-cracked FPB specimens.•A Python-based FE method is developed for the automated fatigue crack modelling.•The simulated failure modes, crack trajectories and fatigue life are validated experimentally.•Repair effects increase with KI/KII, CF...
