Keywords: multiple-site damage, stress intensity factor, crack growth rate, life prediction

Multiple site damage is one of the most representative damage styles in aircraft structure. Staggered riveted lap-joint specimens were employed to simulate the practical structural form and fatigue tests were conducted. Based on the test data and finite element analysis the influence of MSD on crack growth behavior is investigated.
