growth testing and modelling is required. However, there is still a complete lack of i crack propagation in friction stir welds under variable amplitude loading and flight lo investigations have been performed on centre cracked 4 mm thick AA2024-T3 bas regarding the FSW samples, the crack was placed 5 mm out of the weld centre, in the coupons have been tested under simple variable amplitude load sequences, an simulation load history, Falstaff. The fatigue crack propagation was then predicted fracture mechanics software packages. Interaction effects and internal residual stre simulated and than combined in order to evaluate the ability to predict the fatigue c structures under service loading conditions.
