In this communication, a novel approach for a modular description of the response of composite materials and structures is proposed. The modularity is question lies in the ability of the model to be applied to both unidirectional and woven laminates, and to predict the mechanical response in various load cases, from the longest (fatigue) to the fastest (crash). It is achieved thanks to phenomenological description of anelasticity and damage, and a building-blocks vision of long-term viscosity (creep) and short-term viscosity (rate hardening). After a brief description of the general constituents, a crash application is presented.
