In this work we present a short account of the linear theory of thermoelasticity. The exposition of nonlinear thermoelasticity is presented to provide a base for the linear theory. The reader interested in the nonlinear thermoelasticity is referred to the books by . This is a survey article on the modeling of thermoelastic waves in a solid body. The term ''Generalized Thermoelasticity'' stands for a Hyperbolic Thermoelasticity in which a thermomechanical load applied to a body is transmitted in a wave-like manner throughout the body. Only transient thermoelastic waves are included in the survey. First, the basic equations of classical thermoelasticity (based on Fourier heat conduction) are reviewed. Then, starting from continuum thermomechanics, the corresponding equations of the thermoelasticity with one relaxation time [or the Lord‐Shulman (L‐S) theory] are obtained, followed by an analogous set of equations of thermoelasticity with two relaxation times [or the Green‐Lindsay. In this work, a new theory of thermoelasticity has been derived based on fractional order of strain (fraction order Duhamel-Neumann stress-strain relation). A new unified system of differential equ Cited by:

The extended thermoelasticity theory, with one relaxation time, was proposed by Lord and Shulman (Lord and Shulman ) and the temperature dependent thermoelasticity, with two relaxation times, was introduced by Green and Lindsay (Green and Lindsay ). These non-classical theories are termed as generalized theory of Size: KB. theory of linear thermoelasticity and its applications. They introduced the coupling between thermal conduction and elasticity by considering the temperature dependence of the speci c free energy and using a power series expansion of it in terms of strain invariants and temperature. Limiting the expansion to quadratic terms, they. Let the motion of material points in the body be described by the map x = ϕ(X) = x(X) (1) where X is the position of a point in the initial conﬁguration and x is the location of the same point in the deformedFile Size: KB. To address these issues, a new theory, commonly referred to as the theory of hyperbolic thermoelasticity or second sound thermoelasticity, has emerged. In contrast to the classical thermoelasticity, parabolic equation (2) is replaced with a hyperbolic first-order system with and denoting the heat flux and the relaxation tensor, by: 3.
