The normalized stress intensity factor at the crack front is used as fracturecriterion. Comparison of stress intensity factor values at the internal and external positions of repaired quarter-elliptical cornercrack was done, for three repair techniques. The influence of mechanical and geometrical properties of the adhesive layer andthe composite patch on the variation of the stress intensity factor (SIF) at the crack-front was highlighted. The obtained resultsshow that the application of double patch leads to a remarkable reduction of SIF at the crack front, compared to facial and lateralrepairsLire moins >
