In the present study, crack initiation induced by the free‐edge effect in symmetric angle‐ply laminates is investigated. For this purpose, the coupled stress and energy criterion within the framework of finite fracture mechanics is used. In order to obtain the required quantities efficiently the semi‐analytical scaled boundary finite element method is implemented. The obtained effective failure stresses are compared to experimental findings from literature.
