Constitutive settings with regard to energy- and entropy-balances in non-equilibrium thermodynamics: the thermodynamical verification

Abstract Constitutive equations have to be in agreement with the energy- and entropy-balances. For achieving that, the procedure of thermodynamical verification is introduced: Because heat flux and entropy flux as well as the time differentials of internal energy and entropy are not independent of each other, energy- and entropy-balances are connected with each other by so-called internal settings laying down the theoretical frame of the applied material description which is characterized by additional constitutive settings.. For elucidating the procedure of thermodynamical verification, three examples are considered which use different settings.
