Modeling and Analysis of Rayleigh-Type Surface Waves in Elastic Solids with Double Porosity
##submission.downloads##
This investigation examines Rayleigh-type surface waves in an isotropic, homogeneous
elastic half-space possessing a dual-porosity structure. The surface is considered stress-free. From
the general analysis, the frequency equations for elastic media with single porosity are recovered as
a limiting case. Numerical solutions of the derived equations are obtained. Graphical representations
for copper material illustrate the dependence of Rayleigh wave speed and attenuation coefficient on
wave number.
