Influence of the rotation on a generalized magneto-thermoelastic medium for three-phase-lag model

Abstract

Purpose

The purpose of this paper is to investigate the effect of rotation and a magnetic field on the wave propagation in a generalized thermoelastic problem for a medium with an internal heat source that is moving with a constant speed.

Design/methodology/approach

The formulation is applied to a generalized thermoelastic problem based on the three-phase-lag model and Green-Naghdi theory without energy dissipation. The medium is a homogeneous isotropic thermoelastic in the half-space.

Findings

The exact expressions of the displacement components, temperature, and stress components are obtained by using normal mode analysis.

Originality/value

Comparisons are made with the results predicted by the two models in the absence and presence of a magnetic field as well as a rotation. A comparison also is made with the results predicted by the two models for two different values of an internal heat source.
