Damage Process

A model for numerical analysis of interface damage which leads to interface crack initiationand propagation in multi-domain structures under cyclic loading is considered. Modelling of damagetakes into account various relations between interface stresses and displacement gaps providing theresponse of a cohesive zone model, additionally equipped by a kind of viscosity associated to theevolution of the interface damage. Together with repeating loading-unloading conditions, it makesthis damage process to have a fatigue-like character, where the crack appears for smaller magnitudeof the cyclic load than for pure uploading.
