Numerical analysis of a swelling poro-thermoelastic problem with second sound [PDF]

, 2023
In this paper, we analyze, from the numerical point of view, a swelling porous thermo-elastic problem. The so-called second-sound effect is introduced and modeled by using the simplest Maxwell–Cattaneo law. This problem leads to a coupled system which is

Uniqueness for a high order ill posed problem [PDF]

, 2022
In this work, we study a high order derivative in time problem. First, we show that there exists a sequence of elements of the spectrum which tends to infinity and therefore, it is ill posed. Then, we prove the uniqueness of solutions for this problem by

L-p-L-q-Well Posedness for the Moore-Gibson-Thompson Equation with Two Temperatures on Cylindrical Domains [PDF]

, 2020
[EN] We examine the Cauchy problem for a model of linear acoustics, called the Moore-Gibson-Thompson equation, describing a sound propagation in thermo-viscous elastic media with two temperatures on cylindrical domains. For an adequate combination of the

Maximal regularity and global existence of solutions to a quasilinear thermoelastic plate system

, 2012
We consider a quasilinear PDE system which models nonlinear vibrations of a thermoelastic plate defined on a bounded domain in R^n. Well-posedness of solutions reconstructing maximal parabolic regularity in nonlinear thermoelastic plates is established ...

Asymptotic model for the propagation of surface waves on a rotating magnetoelastic half-space

Demonstratio Mathematica
This article is focused on deriving the approximate model for surface wave propagation on an elastic isotropic half-plane under the effects of the rotation and magnetic field along with the prescribed vertical and tangential face loads.

Inverse Design Based on Nonlinear Thermoelastic Material Models Applied to Injection Molding

, 2019
This paper describes an inverse shape design method for thermoelastic bodies. With a known equilibrium shape as input, the focus of this paper is the determination of the corresponding initial shape of a body undergoing thermal expansion or contraction ...

A memory-type thermoelastic laminated beam with structural damping and microtemperature effects: Well-posedness and general decay

Demonstratio Mathematica
In previous work, Fayssal considered a thermoelastic laminated beam with structural damping, where the heat conduction is given by the classical Fourier’s law and acting on both the rotation angle and the transverse displacements established an ...

A thermoelastic contact problem with a phase transition [PDF]

, 2004
We investigate a thermomechanical contact problem with phase transitions. The system of equations consists of a quasistatic momentum balance and a semilinear energy balance.
