Cohesive zone method for failure analysis of scarf patch-repaired composite laminates under bending load

The repair of composite materials has received much attention in recent decades because these materials are used in a wide range of industrial applications owing to their excellent mechanical properties. In this work, the failure of scarf patch-repaired composite laminates subjected to bending loads was experimentally and numerically investigated. Thirty repaired laminates with a scarf angle of 5.7° or 3.8° were prepared and tested under...
