Starting from the concrete problem of the survivability of propellant material, we will present the developments in the modelling of their behaviour in three domains:

1. In two domains where quasistatic loading can be applied, a specific homogenisation procedure will be presented : - For visco-hyperelasticity description of the response of the material; - For debonding descriptions of the response of the material

2. The dynamic domain through a mesoscopic description.

Limitations of and issues with these description will be presented.

*This work is done in collaboration with : - Le Laboratoire de Mécanique et de Physique des Matériaux de l’ENSMA (A. Dragon, C. Nadot, D. Halm) - Le Centre de Morphologie Mathématiques (CMM) de l’ENSMP (D. Jeulin, M. Faessel)
