The composite plates had a (0 degrees/90 degrees)(3) anti-symmetric stacking sequence; the patches were obtained from the same plates and were bonded using an epoxy-based adhesive. The effects of the geometry of the notch were investigated using U-, V-, and square-shaped notches. We varied the notch geometry, investigated single-lap and double-lap repairs, and varied the patch fiber-stacking sequence. Simulations were carried out to analyze the three-dimensional failure progression using ANSYS. The failure loads of the repaired plates increased by 170-304% for single-lap repairs and 240-476% for double-lap repairs compared with the notched plates. The simulated and measured failure loads were in agreement within 0.2-23.6%.eninfo:eu-repo/semantics/closedAccessCompositesEpoxy/EpoxidesFinite Element AnalysisRepairArticle934328341WOS:0003928374000032-s2.0-8499967245110.1080/00218464.2015.1116984Q2Q2
