In questa Nota si provano esistenza, unicità e dipendenza continua per un problema unidimensionale e dipendente dal tempo, relativo a un modello termomeccanico di transizioni di fase strutturali nei solidi. In questo modello si suppone che l'energia libera dipenda da temperatura, deformazioni macroscopiche e anche dalle proporzioni di fase. Si trascurano termini regolarizzanti nella equazione di bilancio del momento e nella legge costitutiva delle proporzioni di fase.
