Une nouvelle stratégie de calcul multi-échelle est proposée pour analyser les structures dont le comportement est décrit á une échelle fine tant en temps qu'en espace (par exemple : les structures composites). Au moins pour un certain nombre de questions, elle devrait se substituer avantageusement aux techniques standards d'homogénéisation et de réanalyse locale qui en général sont limitées au domaine spatial. Le but est ici de décrire les bases de cette approche.
A new multiscale computational strategy is proposed for the analysis of structures which are described at a refined level both in space and in time (for example, composite structures). For certain problems of interest, this new strategy can replace standard homogenization techniques (often coupled with local re-analysis) that are generally limited to the space domain. The aim herein is the description of the basis of the proposed approach.
