Une approche modulaire pour la simulation numérique des composites stratifiés

A novel approach for the modular description of the response of composite materials and structures is proposed. The modularity in question lies in the ability of the model to be applied to both unidirectional and woven laminates, of any type of constituents, and to predict their mechanical response in various load cases, from the longest (fatigue) to the fastest (crash). It is achieved thanks a 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 model, an application to a glass fiber polyamid matrix woven laminate is presented, followed with the response of a door reinforcement made of such a material to a lateral shock.
