The failure analysis consisted of two steps: In the first step, the damaged composite plates used in previous studies were repaired with epoxy-based adhesive and patch. In the second step, the repaired composite plates were loaded with pin and the failure analysis was realized. The four-layered unidirectional carbon/epoxy composite plates were used as composite and patch materials. The layer configuration of the composites was selected as [0 degrees/theta degrees](s) and [0 degrees/theta degrees](2). The numerical study was carried out in ANSYS by using three-dimensional progressive failure codes. As a result of the studies, the failure loads of repaired composite plates were compared with the un-damaged plates. It was determined that the failure loads of adhesively repaired composite plates increased between 238% and 514%.eninfo:eu-repo/semantics/openAccessCompositesRepairFinite Element AnalysisDamage MechanicsJoint DesignStress AnalysisArticle415WOS:0004646928000032-s2.0-8506424627510.1007/s40430-019-1700-4Q2Q3
