Abstract

This paper investigates the possibility of shear wave propagation along the plane surface in the interface of two different types of fibre reinforced media. The upper layer is fibre reinforced and the lower half-space is taken inhomogeneous fibre reinforced. Dispersion equation and condition for maximum energy flow near the surface are obtained in compact form. The dispersion equation coincides with that of Love wave for uniform media. Effect of reinforcement and inhomogeneity on phase and group velocity has been depicted by means of graphs. It is observed that inhomogeneity and reinforcement decreases the phase velocity and presence of reinforcement deviate the group velocity.
