Real 3D Crack-Front and Crack Trajectory Analyses of Single-Side Repaired Thick Aluminium Panels

Abstract:

In this paper, fatigue crack growth trajectories, crack-front shape and life of the single-side repaired thick aluminium panels with glass/epoxy patch are analyzed. This investigation is performed using three dimensional finite element fracture analyses in general mixed-mode conditions (Mode I, II and III). The obtained fatigue crack growth trajectories, crack-front shapes and lives of the repaired panels with the patch lay-ups of [90]4 and [-45]4 are compared with the available experimental results produced by the authors.
