Delamination in cross-ply laminates: Identification of traction–separation relations and cohesive zone modeling

Identification of traction–separation relations is at the forefront of damage and fracture mechanics of composite laminates. Such relations are of particular interest in fracture of laminates consisting of layers of different fiber orientations. In this study, an iterative method based on internal strain measurements and parametric numerical modeling is employed to identify a traction–separation relation in quasi-static mode I dominated...
