Abstract

Purpose

The purpose of this research contribution is to examine the thermoelastic interactions in a fiber-reinforced thermoelastic medium under the action of initial stress and gravity in which, the conventional Fourier’s law is modified, introducing a thermal relaxation parameter in the GN-III model of generalized thermoelasticity.

Design/methodology/approach

The work presented in this manuscript proposes a thermoelastic problem where the Moore–Gibson–Thompson equation is used to model the thermal law. The technique of normal mode is employed to derive the exact expressions of various physical fields under consideration.

Findings

Under the application of moving thermal load, normal displacement, temperature distribution and stress components are calculated numerically with the help of MATLAB software and then presented graphically to support the theoretical formulation.

Originality/value

Field variables are affected by initial stress, gravity, fiber reinforcement, velocity of thermal load and time duration, according to numerical simulations. Some particular cases of interest have also been inferred from the present problem.
