Elastic isotropy of hcp-Fe under Earth core conditions

, 2009
Our first-principles calculations show that both the compressional and shear waves of hcp-Fe become elastically isotropic under the high temperatures of Earth inner core conditions, with the variation in sound velocities along different angles from the c

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 ...

Propagation 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.

Memory-dependent magneto–thermoelasticity for perfectly conducting two-dimensional elastic solids with thermal shock

Journal of Ocean Engineering and Science, 2019
Recently, Yu et al. (2014) proposed a new model in generalized thermoelasticity based on heat conduction with the memory-dependent derivative. The magneto–thermoelastic responses in a perfectly conducting thermoelastic solid half-space is investigated in

Wave Solutions

, 2012
In classical continuum physics, a wave is a mechanical disturbance. Whether the disturbance is stationary or traveling and whether it is caused by the motion of atoms and molecules or the vibration of a lattice structure, a wave can be understood as a ...

Reflection of plane waves from a micropolar thermoelastic solid half-space with impedance boundary conditions

Journal of Ocean Engineering and Science, 2019
In this paper, the governing equations of linear, isotropic, homogeneous and generalized micropolar thermoelasticity are specialized in a plane. The governing equations are solved for plane harmonic wave solutions.

Computational multiscale methods for linear heterogeneous poroelasticity

, 2018
We consider a strongly heterogeneous medium saturated by an incompressible viscous fluid as it appears in geomechanical modeling. This poroelasticity problem suffers from rapidly oscillating material parameters, which calls for a thorough numerical ...

Two-Temperature Generalized Thermoviscoelasticity with Fractional Order Strain Subjected to Moving Heat Source: State Space Approach

Journal of Mathematics, 2015
The theory of generalized thermoelasticity with fractional order strain is employed to study the problem of one-dimensional disturbances in a viscoelastic solid in the presence of a moving internal heat source and subjected to a mechanical load.
