Cohesive Zone Models: A Critical Review of Traction-Separation Relationships Across Fracture Surfaces
TL;DR: In this article, potential-based models have been evaluated for mixed-mode cohesive fracture, and it is shown that these models lead to positive stiffness under certain separation paths, contrary to general cohesive fracture phenomena wherein the increase of separation generally results in the decrease of failure resistance across the fracture surface.
Journal ArticleDOI
Accurate simulation of delamination growth under mixed-mode loading using cohesive elements: Definition of interlaminar strengths and elastic stiffness
TL;DR: In this paper, a methodology for predicting accurately the propagation of delamination under mixed-mode fracture with cohesive elements is proposed, where relations between the interlaminar strengths and the penalty stiffness are proposed which ensure a correct energy dissipation when delamination propagates.
