Abstract Damage generally refers to the more or less gradual development of micro‐voids and micro‐cracks. Damage mechanics is the modelling of these phenomena on a structural analysis scale. In this paper we first recall the non‐linear behaviour models we have developed to model composite laminates. Then we present two examples of implementations of such models in a structural analysis code in order to simulate the inner‐failure of a structure, or to study delamination initiation.
