摘要: Abstract In this study, we analyzed the fatigue behavior of a V-notch crack in an aluminum alloy 7075-T6 plate repaired with bonded composite patch under constant and stepped variable amplitude loading. The effect adhesive disbond on repair performance was analyzed. obtained results confirm need repairing cracks at their early creation for maximum showed that increases width stress ratio have large negative efficiency. latter is low increasing loading blocks but significantly high decreasing blocks.
