Thermoelasticity

In this paper we consider an alternative generalization of classical thermoelasticity to those already available. Restrictions on constitutive equations are discussed with the help of an entropy production inequality proposed by Green and Laws [4]. The work is closely related to that of Müller [3] but the final results are somewhat more explicit. The theory is linearized and a uniqueness theorem is stated. In agreement with Müller [3] it is shown that the linear heat conduction tensor is symmetric and that the theory allows for “second sound” effects.
