Abstract
The present paper is aimed at studying the influence of gravity field on the general model of the generalized thermo-microstretch equations for a homogeneous isotropic elastic half-space solid. The problem is in the context of the Lord-Şhulman and Green-Lindsay theories, as well as the coupled theory. The Finite Element Method is used to obtain the exact expressions for the displacement components, force stresses, temperature, couple stresses and microstress distribution. The variations of the considered variables perpendicular to the axis of rotation are illustrated graphically using MATLAB software. Comparisons are made with the results in the presence and absence of gravity field of a particular case for the generalized micropolar thermoelasticity medium (without microstretch constants) between the three theories. The results obtained are agreement with the previous results obtained with neglecting the new external parameters that predict new results applicable and useful for the related topics as geophysics, biology, acoustics, …, etc.
