Abstract The patch debonding is one of the most serious failure modes of reducing the efficiency of composite repair. In this study, a three-dimensional finite element method is used to analyze the initiation and progression of cohesive failure of the semicircular patch repairing crack emanating from a semicircular notch root. The stress intensity factor and the debonding initiation stress are calculated. The obtained results show that the debonding propagation can be decreased by optimizing the geometrical properties of the composite patch and the adhesive.
