Fatigue crack growth in a panel with 4 stringers and 3-clips, made of AA6156 T6, was modelled numerically using xFEM. The central crack of the length a=17 mm was propagated in the total of 91 steps (in each step crack length increased by 2 mm) and after 14 steps the first clip began to deform. At the same time, crack continued to grow through the base plate, reaching the right and left stringers after 91 steps and beginning to grow along those stringers. Number of cycles for panel with additional 3-clips was higher than for panel with just 4-stringer, (278476 cycles vs. 2649587) cycles, improving fatigue life for cca 5%.
