Fig. 2From: Recent advancements on the phase field approach to brittle fracture for heterogeneous materials and structuresa Coexistence between brittle fracture in the bulk and cohesive debonding of an interface within the context of the phase field approach of fracture. Schematic representation of the traction separation law of the CZM which accounts for the phase field variable. b Mode I CZM traction \(\sigma \) vs. \(g_n\). c Mode II CZM traction \(\tau \) vs. \(g_t\)Back to article page
