Abstract

The influences of planar and corrugated free surfaces on bright solitary-like shear horizontal (SH) waves
propagating on a nonlinear elastic layer over a rigid substratum are compared. The amplitude of irregularity of the
free surface is co nsidered as small compared to the average thickness of the layer. The layers consist of
compressible, homogeneous and isotropic materials. A generalized nonlinear Schrödinger (GNLS) equation for
the nonlinear modulation of SH waves is obtained via an asymptotic perturbation method. A comparative study
between the influences of regular and irregular layers on the bright solitary-like SH waves is presented graphically.
