Recovery of a space-dependent vector source in thermoelastic systems [PDF]

open access: yes, 2014
In this contribution, an inverse problem of determining a space-dependent vector source in a thermoelastic system of type-I, type-II and type-III is studied using information from a supplementary measurement at a fixed time.

Time decay in dual-phase-lag thermoelasticity: critical case  [PDF]

open access: yes, 2018
This note is devoted to the study of the time decay of the onedimensional dual-phase-lag thermoelasticity. In this theory two delay parameters tq and t¿ are proposed. It is known that the system is exponentially stable if tq < 2t¿ [22].

On the flexural and extensional thermoelastic waves in orthotropic plates with two thermal relaxation times

open access: yesJournal of Applied Mathematics, Volume 2004, Issue 1, Page 69-83, 2004., 2004
Analysis for the propagation of plane harmonic thermoelastic waves in an infinite homogeneous orthotropic plate of finite thickness in the generalized theory of thermoelasticity with two thermal relaxation times is studied. The frequency equations corresponding to the extensional (symmetric) and flexural (antisymmetric) thermoelastic modes of vibration

Reflection and transmission at the boundary surface of modified couple stress thermoelastic media

open access: yesInternational Journal of Applied Mechanics and Engineering, 2016
In this paper the reflection and transmission at a plane interface in modified couple stress generalized thermoelastic solid half spaces in the context of Loard-Shulman (LS) and Green-Lindsay (GL) theories in welded contact are investigated.

On the existence and decay in a new thermoelastic theory with two temperatures [PDF]

open access: yes, 2022
In this work, we study a new two-temperatures thermoelastic model. Both thermodynamic and conductive temperatures are included, being related by means of an elliptic or parabolic equation.

Blowup of solutions with positive energy in nonlinear thermoelasticity with second sound

open access: yesJournal of Applied Mathematics, Volume 2004, Issue 3, Page 201-211, 2004., 2004
This work is concerned with a semilinear thermoelastic system, where the heat flux is given by Cattaneo′s law instead of the usual Fourier′s law. We will improve our earlier result by showing that the blowup can be obtained for solutions with “relatively” positive initial energy.

Multidimensional Thermoelasticity for Nonsimple Materials -- Well-Posedness and Long-Time Behavior [PDF]

open access: yes, 2016
An initial-boundary value problem for the multidimensional type III thermoelaticity for a nonsimple material with a center of symmetry is considered. In the linear case, the well-posedness with and without Kelvin-Voigt and/or frictional damping in the ...

n2 of dissipative couplings are sufficient to guarantee the exponential decay in elasticity [PDF]

open access: yes, 2022
In this paper, we prove that the solutions to the problem determined by an elastic material with n2 coupling dissipative mechanisms decay in an exponential way for every (bounded) geometry of the body, where n is the dimension of the domain, and whenever

Some remarks on growth and uniqueness in thermoelasticity

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 10, Page 617-623, 2003., 2003
We use the Lagrange identity method and the logarithmic convexity to obtain uniqueness and exponential growth of solutions in the thermoelasticity of type III and thermoelasticity without energy dissipation. As this is not the first contribution of this kind in this theory, it is worth remarking that the assumptions we use here are different from those

Thermomechanical constraints and constitutive formulations in thermoelasticity

open access: yesMathematical Problems in Engineering, Volume 2003, Issue 4, Page 153-171, 2003., 2003
We investigate three classes of constraints in a thermoelastic body: (i) a deformation‐temperature constraint, (ii) a deformation‐entropy constraint, and (iii) a deformation‐energy constraint. These constraints are obtained as limits of unconstrained thermoelastic materials and we show that constraints (ii) and (iii) are equivalent.
