Thermodynamical admissibility of a set of constitutive equations coupling elasticity, isotropic damage and internal sliding

摘要

The theoretical framework of irreversible processes thermodynamics is nowadays widely used for formulating constitutive laws. Both the physical and the thermodynamical consistency of a constitutive model can be ensured. A unique condition gathering the first and the second thermodynamics principles, known as the Clausius-Duhem-Truesdell inequality, allows checking the thermodynamical admissibility of a constitutive model. In this paper, the authors are focused on proposing a proof of the thermodynamical admissibility of a set of constitutive equations coupling elasticity, isotropic damage and internal sliding.
