Edge wave propagation in an initially stressed dry sandy plate

摘要

The present study analytically deals with the propagation of plane waves at the edge in an initially stressed dry sandy bounded plate. The analytical solutions for potential function and displacement components have been derived separately. The dispersion relation has been obtained in a simplified form with the help of suitable boundary conditions. Numerical computation has been carried out to show the influence of wave number, sandiness parameter and initial stresses and depicted by means of graphs. A comparative study has been made to elucidate the effect of parameters on the phase velocity with a case where the considered plate is composed of isotropic material.
