Thermodynamics of Solids Under Stress

Abstract

This expository paper discusses how the equilibrium thermodynamics of an ideal elastic solid differs from that of a fluid. Because at least some species are immobile, there is no unique Gibbs energy. There are six independent finite strain parameters, n h referred to a chosen reference state. Thermodynamic manipulations are straightforward if stresses t k are defined conjugate to the rj k, but these can be identified with the Cauchy stresses, aA, only in the reference state. Typical experimental conditions are described directly by the a h which have to be related to the t k before experimental quantities like C p can be related to formally derived quantities like C t. © 1970, Walter de Gruyter.
