Sommario

Si caratterizza un solido termoelastico riguardando la seconda legge della termodinamica come una legge supplementare di conservazione compatibile con le equazioni del moto. Si ottengono delle condizioni sufficienti per l'iperbolicità del sistema base che può essere posto in forma simmetrica e conservativa.

Summary

We characterize a thermoelastic solid by considering the entropy law as a supplementary conservation law consequence of the laws of motion. Sufficient conditions in order the governing equations to be a hyperbolic system are pointed out.
