A new material is created, named “char”, and its mechanical properties are diminished in comparison to the virgin material [1, 2]. Thus, in order to have a proper simulation of the phenomena leading to the diminution of mechanical properties, it is necessary to take into account the thermal degradation. This degradation depends on temperature and also on heat transfers taking place into the material. As the thermally damaged material has diminished mechanical properties in comparison to virgin material, thermal degradation is considered as a supplementary mechanical damage. A significant aim is therefore to obtain a predictive model taking into account these coupled phenomena whi...
