              <p>Une méthode basée sur l’apprentissage non-supervisé est développée afin de réduire les calculs non-linéaires dans la méthode FE 2. La technique proposée ici crée des groupes (clusters) de points de Gauss macroscopiques qui sont supposés être dans des états mécaniques proches, les variables internes sont prises en compte dans cette classification en contrôlant le nombre des clusters. Ensuite, un seul calcul non linéaire microscopique de volume élémentaire représentatif (VER) est effectué pour chaque cluster. La technique a montré des facteurs d’accélération de l’ordre de 20 pour des applications sur des composites anélastiques.</p>
