Impact of rotation on a micro-elongated thermoelastic solid subjected to a load from an overlying liquid layer according to various theories

Abstract

Abstract The objective of this study is to examine how the presence of a fluid layer affects thermoelastic behavior of a micro-elongated solid undergoing rotation utilizing the coupled theory (CT) doesn’t contain any relaxation times, the Lord-Shulman (L-S) theory also the model of duple-phase-lag (DPL). Normal mode analysis has been utilized to transform partial differential equations to ordinary differential equations. Subsequently, numerical computations have been performed, and the outcomes have been visualized through graphical representation. In both with and without rotation, a comparison is made among the coupled theory, the (L-S) theory, and the (DPL) model. It is watched that rotation significantly impacts all physical quantities, demonstrating a substantial influence.
