In this research, the stress intensity factor in repairing a single crack edge of the aluminum plate has been evaluated by the combined method of stop holes and composite patch and the comparison of this method with the stop hole method and the composite patch has been investigated. In this study, by drilling holes on both sides of the crack tip in the method of stop holes, repairing the plate with one-sided composite patches made of boron and glass epoxy in the method of repairing with composite patches and simultaneously applying stop holes and composite patches in The combined method, which is modeled in ۳D in Abaqus software, examines the results .the results show that the combined method of stop holes on both sides of the crack and the composite patch is more efficient than the repair method with stop holes and composite patches.
