L'objectif de ce projet de recherche est le développement de simulations numériques de l'endommagement de propergols solides, qui sont dédiés à la propulsion anaérobique, afin d'identifier quelles propriétés affectent leur comportement. Pour étudier l'effet de la géométrie des différentes particules énergétiques, des microstructures 3D sont générées avec une dispersion aléatoire d'inclusions monomodales, sphériques ou polyédriques, à très forte fraction volumique (55%). Dans le cas des sphères, les propriétés élastiques des volumes élémentaires représentatifs (VER) sont confrontées à un modèle analytique et à des caractérisations expérimentales de composites modèles, démontrant une cohérence remarquable entre les trois approches. Par la sui...
