In this paper, the authors study the thermodynamics of nonlinear materials with internal state variables whose temporal evolution is governed by ordinary differential equations, and employ a method developed by Coleman and Noll to find the general restrictions which the Clausius-Duhem inequality places on response functions.
Abstract
This is a study of the thermodynamics of nonlinear materials with internal state variables whose temporal evolution is governed by ordinary differential equations. After employing a method developed by Coleman and Noll to find the general restrictions which the Clausius—Duhem inequality places on response functions, we analyze various types of dynamical stability that can be exhibited by solutions of the internal evolution equations. We also discuss integral dissipation inequalities, conditions under which temperatures can be associated with internal states, and the forms taken by response functions when the material is a fluid.

Models for one-variant shape memory materials based on dissipation functions

TL;DR: In this article, simple models for the macroscopic behavior of shape memory materials whose microstructure can be described as a mixture of two phases are derived on the basis of a free energy and a dissipation function.

A phenomenological theory of transformation superplasticity

TL;DR: In this paper, a phenomenological theory of transformation superplasticity is presented from the point of view of thermomechanics, where the stretching tensor and entropy density are decomposed into the elastic part and the part due to the super-plastic process.

Internal Variables in Non-Equilibrium Thermodynamics

TL;DR: The concept of internal variables is axiomatically introduced into nonequilibrium thermodynamics for avoiding small state spaces showing after effects as mentioned in this paper, and the connection between internal variables, projectors onto equilibrium subspace, and accompanying processes is demonstrated for discrete systems.

The Thermodynamics of Elastic Materials with Heat Conduction and Viscosity

TL;DR: The basic physical concepts of classical continuum mechanics are body, configuration of a body, and force system acting on a body as mentioned in this paper, which can be expressed as follows: a body is regarded as a smooth manifold whose elements are the material points; a configuration is defined as a mapping of the body into a three-dimensional Euclidean space, and a force system is defined to be a vector-valued function defined for pairs of bodies.
