Sommario

Si studiano continui per i quali esiste una configurazione locale (variabile nel tempo) e a partire dalla quale va misurata istante per istante la deformazione elastica. Si specificano le relazioni permesse dalla disguaglianza di Clausius Duhem e dal principio di obbiettività e si adattano al caso alcune definizioni ed un teorema di Coleman e Gurtin sui continui con parametri interni.

Summary

We consider continua for which a local configuration exists, whence the instantaneous elastic strain must be measured. Relations involving stress, strain and strain rate are indicated, which are compatible with objectivity and with the Clausius-Duhem inequality. Definitions and a theorem of Coleman and Gurtin regarding continua with internal parameters are adapted to advantage.
