Surface Wave Propagation at the Interface between an Inviscid Liquid Layer and a rotating Micropolar Elastic Solid with Stretch

This article investigates the impact of angular rotation on surface-wave propagation at the interface between an inviscid liquid layer and a rotating micropolar elastic solid with stretch. The surface-wave secular equation is obtained analytically using the plane-harmonic solution method after the mathematical model has been developed. It is noticed that for symmetric modes of surface waves, the liquid effects and the micro-stretch do not manifest simultaneously. Using MATLAB software, the impacts of the solid's angular rotation and the liquid layer's thickness on the symmetric mode of surface waves are illustrated for a specific model. The velocity of surface waves at the boundary between the liquid and the micropolar elastic solid diminishes as the angular rotation increases and vanishes at the boundary with the microstretch elastic solid, while it rises with greater layer thickness. The wave velocities observed in non-rotating solids exceed those found in rotating solids. In contrast to the symmetric mode of the physical model under consideration, there is no substantial research on the anti-symmetric mode of surface waves.
