Abstract

Love-type wave propagation in a piezoelectric layer bonded by a layer of fiber-reinforced viscoelastic and a heterogeneous fluid-saturated cracked dual porous half-space is investigated in this paper. The heterogeneity of fracture double porous medium is assumed to be exponential distribution functions. With the help of the variable separation technique, the governing equations of each layer and half-space are solved to get the solutions of mechanical displacement and electric potential function. The results are confirmed by comparison with the classical case of Love wave, and special cases of the problem are also discussed. The phase velocity is calculated numerically and plotted graphically for various material characteristics of the layers and half-space. The analysis reveals that the phase velocity rises with an increase in viscoelastic parameters and the dielectric constant, as well as the reinforcement parameters, while it decreases with an increase in the inhomogeneity parameter, piezoelectric constant, and thickness ratio parameter. A comparative study has also been conducted to analyze the effect of these parameters on the phase velocity using two piezoelectric materials, PZT-4 and PZT-7. The importance of parameter effects increases for Love-type waves with shorter wavelengths and small guiding layer thicknesses.
