The Behavior of Shear Waves in the Composite Multi-Material Structure with the Periodic Asymmetric Surfaces

The behavior of surface horizontally polarized shear waves (SH waves) in the composite multi-material structure with a periodic irregular and interface is investigated analytically present study. To unravel enshrouded features SH-wave propagation multi-layer structure, we consider model three distinct materials. In schematic problem, guiding layer (M-I) contains fluid-saturated porous materials finite thickness, intermediate (M-II) fiber-reinforced composites, substrate functionally graded orthotropic (M-III). free M-I upper medium are considered to be on basis, but M-II M-III supposed regular. dispersion relation obtained demonstrated graphically for phase velocity versus wave number analyze proposed structure. acquired results resemble typical Love results, confirming validity work. current work provides comprehensive evaluation impact regular boundaries SH waves. It notable that reinforced parameters, initial stress, porosity consistent both scenarios. More than irregularity surface, had an velocity. useful understand compositions mountain surface.
