Rayleigh Wave Propagation in a Rotating Functionally Graded Fiber-Reinforced Medium Subject to Magnetic and Gravitational Fields

An analytical investigation is conducted on Rayleigh wave propagation in a rotating fiberreinforced functionally graded (FG) half-space subjected to magneto-gravitational effects. The orientation of the magnetic field is configured to facilitate a two-dimensional treatment of the governing equations. A transcendental dispersion equation is established, which is shown to reduce to well-known classical solutions under limiting conditions. Finally, parametric studies are performed to quantify the influence of rotation, gravity, and material grading on the phase velocity, with the findings presented graphically.
