Effect of magnetic field on piezo-thermoelastic medium with three theories
Results in Physics, 2017 In the present paper, we use the classical dynamical coupled theory, Lord-Shulman theory with one relaxation time, and Green-Lindsay with two relaxation times of thermoelasticity to study the influence of magnetic field on piezo-thermoelastic medium. The

Global Non-Existence of a Coupled Parabolic–Hyperbolic System of Thermoelastic Type with History
Mathematics, 2023 We consider two abstract systems of parabolic–hyperbolic type that model thermoelastic problems. We study the influence of the physical constants and the initial data on the nonexistence of global solutions that, in our framework, are produced by the ...

Magneto-viscoelastic plane waves in rotating media in the generalized thermoelasticity II
International Journal of Mathematics and Mathematical Sciences, 2005 A study is made of the propagation of time-harmonic magneto-thermoviscoelastic plane waves in a homogeneous electrically conducting viscoelastic medium of Kelvin-Voigt type permeated by a primary uniform external magnetic field when the entire medium ...

Asymptotic solutions for generalized thermoelasticity with variable thermal material properties
Archives of Mechanics, 2016 In this paper, a unified generalized thermoelastic solution with variable thermal material properties is proposed in the context of different generalized models of thermoelasticity, including thermoelasticity with one thermal relaxation time (LS theory),

Eigenvalue approach to coupled thermoelasticity in a rotating isotropic medium
Results in Physics, 2018 In this paper the linear theory of the thermoelasticity has been employed to study the effect of the rotation in a thermoelastic half-space containing heat source on the boundary of the half-space.

Theoretical Study on Thermal Stresses of Metal Bars with Different Moduli in Tension and Compression
Metals, 2022 Extensive studies have shown that engineering materials, including metals and their oxides, will present different mechanical properties in tension or compression; however, this difference is generally neglected due to the complexity of the analysis.

Advanced Science, EarlyView.Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...
