Orthotropic magneto-thermoelastic solid with higher order dual-phase-lag model in frequency domain

Parveen Lata and Himanshi

Abstract

Here, in this research we have studied a two dimensional problem in a homogeneous orthotropic magnetothermoelastic medium with higher order dual-phase-lag heat transfer with combined effects of rotation and hall current in generalized thermoelasticity due to time harmonic sources. As an application the bounding surface is subjected to uniformly distributed and concentrated loads (mechanical and thermal source). Fourier transform technique is used to solve the problem. The expressions for displacement components, stress components and temperature change are derived in frequency domain. Numerical inversion technique has been used to obtain the results in physical domain. The effect of frequency has been depicted with the help of graphs.
