Direct Approach to Thermoelasticity
Journal of Thermal Stresses, 1979The Laplace transforms with respect to time of the governing equations of one-dimensional thermoelasticity are obtained, with the displacement and temperature fields coupled. Elimination of the Laplace transform of either field variable between the resulting linear, simultaneous, and coupled ordinary differential equations results in ordinary ...

A novel generalized thermoelasticity with higher-order time-derivatives and three-phase lags
, 2019In this work, a modified thermoelastic model of heat conduction, including higher order of time derivative, is constructed by extending the Roychoudhuri model (TPL) (Choudhuri, 2007).

The physics of thermoelastic involves both thermal and structural phenomena that require to be handled together. Consequently, thermoelastic analysis has to be considered as an integral process including both related disciplines with close interaction of the models. This interaction imposes an important and often overlooked constraint: Making decisions

SPIE Proceedings, 1987
It has been demonstrated that the response of the SPATE 8000 depends not only on the alternating stress experienced by the object being examined but also, to a small extent, upon the mean stress about which the alternating stress is superposed. The 'thermoelastic constant' varies linearly with mean stress for each of the aluminium, steel and titanium ...

On fractional thermoelasticity
Mathematics and Mechanics of Solids, 2011Two general models of fractional heat conduction for non-homogeneous anisotropic elastic solids are introduced and the constitutive equations for thermoelasticity theory are obtained, uniqueness and reciprocal theorems are proved and the convolutional variational principle is established and used to prove a uniqueness theorem with no restriction on ...

Elasticity and Thermoelasticity
2017This chapter presents an overview of the historical development of the three-dimensional theories of elasticity and thermoelasticity. While it is not an exhaustive coverage of this subject, the material presented herein is introduced as a means of preparing the reader for the subjects to come that deal with the inelastic deformations that occur in ...

Abstract Constitutive equations for a linear thermoelastic dielectric are derived from the energy balance equation assuming dependence of the stored energy function on the strain tensor, the polarization vector, the polarization gradient tensor and entropy.

This work presents an extensive discussion of initial boundary value problems in thermoelasticity. First, the classical hyperbolic–parabolic model with Fourier’s law of heat conduction is considered giving results on linear systems, nonlinear systems, in one or more space dimensions, in particular discussing the asymptotic behavior of solutions as time

THERMOELASTICITY AND CONTACT [PDF]
Journal of Thermal Stresses, 1999 Thermoelastic deformations can have a significant effect on the contact between elastic bodies, particularly in cases where the thermal boundary conditions at the interface are influenced by the contact pressure. In the classical Hertzian problem, the size of the contact area depends on the magnitude and direction of heat flow between the bodies ...
