摘要：
In this study, finite element method is used to investigate crack propagation of stiffened aluminum panels repaired with composite patches. For this purpose, 3-D crack-front in general mixed-mode conditions is considered for the analyses. The cracks are considered to be near the stiffener around a rivet and are capable to propagate under a cyclic loading. Effects of rivets distances and their diameter on the crack growth life of repaired panels are investigated. Moreover, the obtained crack-front shapes at various crack growth steps, crack trajectories and life of the unrepaired and repaired panels with various glass/epoxy patch lay-ups are discussed.
