This paper presents a theoretical study of the propagation behaviour of surface Love waves in nonhomogeneous functionally graded elastic materials, which is a vital problem in acoustics. The elastic properties (shear modulus) of a semi-infinite elastic half-space vary monotonically with the depth (distance from the surface of the material). Two Love wave waveguide structures are analyzed: 1) a nonhomogeneous elastic surface layer deposited on a homogeneous elastic substrate, and 2) a semi-infinite nonhomogeneous elastic half-space. The Direct Sturm-Liouville Problem that describes the propagation of Love waves in nonhomogeneous elastic functionally graded materials is formulated and solved 1) analytically in the case of the step profile, exponential profile and 1cosh 2 type profile, and 2) numerically in the case of the power type profiles (i.e. linear and quadratic), by using two numerical methods: i.e. a) Finite Difference Method, and b) Haskell-Thompson Transfer Matrix Method.The dispersion curves of phase and group velocity of surface Love waves in inhomogeneous elastic graded materials are evaluated. The integral formula for the group velocity of Love waves in nonhomogeneous elastic graded materials has been established. The results obtained in this paper can give a deeper insight into the nature of Love waves propagation in elastic nonhomogeneous functionally graded materials.

“…The performance of materials in device applications has played a vital role in enhancement of study involving smart materials. Study of seismic surface waves propagating in bedded structure (comprising of piezo-composite materials) has gained considerable attention in the recent past because of its practical applications in fields of acoustic devices, non-destructive evaluation, sensor designing etc [1][2][3]. Moreover, Surface Acoustic Wave has found its great importance in signal processing as well as in compound detection of liquids or gases.…”

We propose an analytical solution for the propagation of Love-type surface seismic waves in a piezo-composite smart structure. A model describing the Love-type wave propagation in the piezomagnetic waveguide is considered. The model is comprised of piezomagnetic layer lying on a lossy viscoelastic substrate. In this regard a direct Sturm-Liouville problem has been formulated and solved. Complex dispersion equations have been derived for both magnetically open and short cases. For each case we have obtained two nonlinear equations containing two unknowns and various parameters. These nonlinear equations are solved using suitable numerical method implemented in Mathematica 9.0 software. Further, the obtained frequency relations are matched with the classical case of Love wave to validate the problem. The influence of different parameters (thickness of the layer, frequency, piezomagnetic coefficient and elastic parameter) on the phase velocity and attenuation of Love-type waves are discussed and delineated through graphs. The results have immense applications in non-destructive evaluation, designing of viscosity sensors, SAW devices, biosensors and chemosensors.

“…Surface love waves in a layered medium have been successfully applied in many fields like nondestructive testing (NDT) and material characterization [1][2][3], seismology, and earthquake engineering [4][5][6][7][8][9]. Recently, the use of love waves devices for the development of viscosity sensors [10][11][12][13][14][15], chemical sensors [16], and biosensors [17][18][19][20] has been extensively investigated.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. This is an author-deposited version published in: https://sam.ensam.eu Handle IDThis work presents a theoretical method for surface love waves in poroelastic media loaded with a viscous fluid. A complex analytic form of the dispersion equation of surface love waves has been developed using an original resolution based on pressure-displacement formulation. The obtained complex dispersion equation was separated in real and imaginary parts. MATHEMATICA software was used to solve the resulting nonlinear system of equations. The effects of surface layer porosity and fluid viscosity on the phase velocity and the wave attenuation dispersion curves are inspected. The numerical solu-tions show that the wave attenuation and phase velocity variation strongly depend on the fluid viscosity, surface layer porosity, and wave frequency. To validate the original theo-retical resolution, the results in literature in the case of an homogeneous isotropic sur-face layer are used. The results of various investigations on love wave propagation can serve as benchmark solutions in design of fluid viscosity sensors, in nondestructive testing (NDT) and geophysics.
