Propagation of Edge Wave in Homogeneous Viscoelastic Sandy Media

The objective of this work is to investigate the propagation characteristics of edge wave in a composite structure comprised of two uniformly homogeneous viscoelastic incompressible sandy plates of finite width and infinite extent. An analytical approach is used to deduce the closed form of frequency equation concerning to phase as well as damped velocities and analyzed the various affecting parameters. The effects of influencing parameters such as viscoelastic parameter, sandy parameter of both plates and wave number on the phase as well as damped velocities of edge wave are depicted graphically with the help of numerical simulation. It has been found that all the affecting parameters have significant effects on the edge wave propagation in the composite structure.
