Scattering of plane waves from stress-free boundary surface of a microstretch elastic solid half-space containing voids

Abstract

Abstract Scattering phenomena of plane coupled waves from stress-free boundary surface of a microstretch elastic solid half-space containing uniform distribution of voids have been investigated. Using appropriate boundary conditions and Snell's law, the reflection coefficients corresponding to various reflected \textcolor{red}{sets of coupled} waves and their corresponding energy ratios have been presented. One of the boundary conditions leads to the vanishing of a cross-coupling parameter between curvature tensor and voids. Numerical computations have been carried out for a specific model and the variation of all the reflection coefficients and \textcolor{red}{their} corresponding energy ratios is depicted graphically against the angle of incidence. Some special cases have been reduced from the present model and discussed.
