Response Due To Impulsive Force In Generalized Thermomicrostretch Elastic Solid

open access: yesInternational Journal of Applied Mechanics and Engineering, 2015
A two dimensional Cartesian model of a generalized thermo-microstretch elastic solid subjected to impulsive force has been studied. The eigen value approach is employed after applying the Laplace and Fourier transforms on the field equations for L-S and ...

Fractional-Order Thermoelastic Wave Assessment in a Two-Dimensional Fiber-Reinforced Anisotropic Material

open access: yesMathematics, 2020
The present work is aimed at studying the effect of fractional order and thermal relaxation time on an unbounded fiber-reinforced medium. In the context of generalized thermoelasticity theory, the fractional time derivative and the thermal relaxation ...

Laser Short-Pulse Effect on Thermodiffusion Waves of Fractional Heat Order for Excited Nonlocal Semiconductor

open access: yesAdvances in Condensed Matter Physics, 2022
In this work, the thermal effect of a laser pulse is taken into account when mechanical-thermodiffusion (METD) waves are studied. The nonlocal semiconductor material is used when interference between holes and electrons occurs.

Analysis of De-Levie’s model via modern fractional differentiations: An application to supercapacitor

open access: yesAlexandria Engineering Journal, 2019
De-Levie’s model has become an indispensable model for knowing a porous electrode because electrochemical supercapacitors provide electrical energy storage and they use nanoporous electrodes to store large amounts of charge.

Fourier-Laplace Transform and Isomonodromic Deformations

open access: yesFunkcialaj Ekvacioj, 2016
Using the Fourier-Laplace transform, we describe the isomonodromy equations for meromorphic connections on the Riemann sphere with unramified irregular singularities as those for connections with a (possibly ramified) irregular singularity and a regular singularity. This generalizes some results of Harnad and Woodhouse.

The boundary value problem of a three-dimensional generalized thermoelastic half-space subjected to moving rectangular heat source

open access: yesBoundary Value Problems, 2019
This paper deals with a new mathematical model of three-dimensional generalized thermoelasticity which has been improved using Lord–Shulman theory. The governing equations on non-dimensional forms have been applied to a three-dimensional half-space ...
