A Study of Magnetoelastic Rayleigh Wave Propagation in a Three Layered Medium

Bishnupada Barik, Sarbani Chakraborty

Abstract


The propagation of Rayleigh-type waves in a three-layered medium is studied analytically in the context
of linear magnetoelasticity. The intermediate layer is one of nite thickness, bounded on both sides by
layers of very large depths,all three layers assumed to be perfect conductors of electricity. Dispersive
Rayleigh-waves are found to exist under an initially uniform magnetic eld,transverse to the displacement
components. Numerical studies show the eect of the eld intensity, and the depth of the middle-layer
on the velocity of the propagating waves.


Keywords
