Abstract : A method of axiomatically deriving a form of the second law of thermodynamics appropriate to continuum mechanics from a general statement of the law is discussed; such a proceedure logically leads to the existence of two temperatures and a modified form of the Clausius-Duhem inequality. It is then shown that for a certain class of materials the inequality can hold only if the two temperatures are always the same and thus that for such materials the usual form of the Clausius-Duhem inequality is appropriate. Finally it is shown that a simple material with memory falls into this class of materials. (Author)
