Abstract	Dans le milieu aeronautique, la simulation numerique s'est largement imposee dans le developpement industriel des systemes complexes. De la conception au suivi en service, les simulations numeriques sont nombreuses et variees. Afin de proposer des methodes alternatives aux methodes de calcul intensif, la reduction de modele permet de reduire considerablement le cout de la resolution numerique des problemes non lineaires en projetant les equations aux derivees partielles sur une base reduite. De plus, la description des phenomenes physiques requiert une loi de comportement elaboree dont une simplification est consideree en exploitant une partie restreinte du domaine spatial. Les etudes effectuees ont pour but d'apporter certains developpements a la methode incrementale et adaptative A Priori Hyper Reduction dans le cas des materiaux heterogenes. Ces developpements sont integres dans le code elements finis Z-set et utilises pour traiter une serie d'exemples academiques sur des structures composites.
