We study the thermoelastic system for material which are partially thermoelastic. That is, a material divided into two parts, one of them a good conductor of heat, so there exists a thermoelastic phenomenon. The other is a bad conductor of heat so there is not heat flux. We prove for such models that the solution decays exponentially as time goes to infinity. We also consider a nonlinear case.
Studiamo il sistema termoelastico per materiali che siano parzialmente termoelastici. Consideriamo cioè un materiale diviso in due parti, una delle quali sia un buon conduttore di calore, in modo che ivi esistano fenomeni termoelastici. L'altra parte materiale è un cattivo conduttore di calore e quindi non esiste il flusso di calore. In questo lavoro dimostriamo che per tali modelli la soluzione decade esponenzialmente a zero quando il tempo tende all'infinito. Studiamo anche il caso non lineare.
