Response of shear wave from a corrugated interface between elastic solid/viscoelastic half-spaces

Abstract The propagation of plane shear wave at a corrugation interface between elastic solid and viscoelastic liquid half‐spaces has been investigated. Adopting Rayleigh's method of approximation, the reflection and refraction coefficients corresponding to reflected and refracted SH‐waves have been derived for the first order of approximation of the corrugated interface. These coefficients are derived in the closed form for a periodic interface. Numerical computation has been performed for a particular model and the results are depicted graphically. The results of Asano ( Bull. Earthquake Res. Inst. 1960; 38 (2):177–197) and Kielczynski and Pajewski ( J. Acoust. Soc. Am. 1987; 81 (3):599–605) are recovered from this study.
