The structural behavior at the interface between two surfaces of ductile, brittleor quasi-brittle materials is studied by a new analytical elasto-plastic damagingmodel. The model is developed in the framework of a thermodynamically consistenttheory. The Helmholtz free energy is written to predict the materials’ hardening orsoftening. An isotropic damage is considered and the possible effects of dilatancyare taken into account including non-associative flow rules. The interface laws arepresented both in a rate and a discrete incremental form. The analytical formulationis then implemented into a finite element code and two structural members arestudied to validate the model. The numerical results are compared to experimentaldata available in literature. It is demonstrated that the new model is general and itincludes the continuum damage mechanics and the elastoplasticity as limit cases.
