Green-Lindsay thermoelasticity for double porous materials

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
The main purpose of this paper is to obtain new results in the thermoelasticity for double porous materials, starting from the classical theory of Green-Lindsay’s elasticity. The novelty of the proposed method consists in proving a reciprocal theorem and

Propagation of thermoelastic impulse through a cylindrical waveguide under sidewall heat interchanging

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The paper is devoted to a study of coupled harmonic thermoelastic impulse guided propagation through an infinite circular cylinder. Heat interchanging is supposed to take place between sidewall of the waveguide and environment.

Second sound thermoelastic stability of a string/beam structure [PDF]

arXiv, 2022
In this paper we study the one dimensional thermoelastic transmission problem in a special string/beam structure: the two components are coupled at an interface (identified to $0$). Either the string or the beam is supposed thermoelastic, the heat flux is given by the Cattaneo's law instead of the usual Fourier's law. We prove that the the energy decay

Thermoelastic Damping in Micro- and Nano-Mechanical Systems [PDF]

Phys. Rev. B 61, 5600 (2000)., 1999
The importance of thermoelastic damping as a fundamental dissipation mechanism for small-scale mechanical resonators is evaluated in light of recent efforts to design high-Q micrometer- and nanometer-scale electro-mechanical systems (MEMS and NEMS). The equations of linear thermoelasticity are used to give a simple derivation for thermoelastic damping ...

An Analysis of the Photo-Thermoelastic Waves Due to the Interaction between Electrons and Holes in Semiconductor Materials under Laser Pulses

Mathematics, 2022
In this paper, the interaction between holes and electrons in semiconductor media is analyzed based on the existing mathematical–physical model. The elasto-thermodiffusion (ETD) theory, according to photothermal (PT) transport processes, has been used to

Effects of the Nonlocal Thermoelastic Model in a Thermoelastic Nanoscale Material [PDF]

Mathematics, 2022
In this work, a novel nonlocal model without energy dissipations is presented to investigate the impacts of the nonlocal thermoelastic parameters in a nanoscale material by the eigenvalue approach. The basic equations are applied under the Green and Naghdi model without energy dissipations.
