SH-Wave Propagation in Double Layers Imperfectly Bonded over a Dry Sandy Half-Space
Mohd Sadab, Santimoy Kundu
Abstract
The present paper deals with the analytical study of shear horizontal (SH)-wave propagation consisting of a microstructural coupled stress layer over a dry sandy half-space beneath the orthotropic viscoelastic layer with imperfect interfaces. The rigidity and density of the sandy medium are assumed to be exponential distribution functions. Dispersion equations for SH-wave propagation have been derived using suitable boundary conditions in the absence and presence of imperfection parameters. In a particular case, the dispersion equation is reduced to the classical Love wave equation, which validates the present mathematical model. The effect of various parameters in the current model on the phase velocity and damped velocity are discussed in the presence and absence of imperfect interfaces. Numerical computations were carried out for involved parameters and illustrated with the help of graphs.
