Generalized interfaces enabling macroscopic modeling of structural adhesives and their failure

• Generalized interface (cohesive zone and elasticity) Coupling of anisotropic cohesive membrane damage variables for an interaction Application to brittle interfaces in adhesive bonding Influence coupling illustrated by numerical example This contribution presents a geometrically linear thermodynamically consistent model generalized mechanical interfaces. The interface’s response is kinematically non-coherent, i.e. allows displacement jump failure, kinetically traction jumps across the damage. ensues from interfacial (in)elasticity formulation which introduces additional stiffness stresses under in-plane stretch interface. degradations are coupled via determined different deformation modes account their interaction. A applies presented adhesively two substrates. By subjecting small prior performing peel test, influence on illustrated.
