A theoretical analysis is performed on the behaviors of the internal scattered wave in the case where a two-dimensional plane Rayleigh wave is incident to an acute- or obtuse-angled wedge. By using the theory in our preceding research (1984), the distributions of energy densities and lines of constant phase of scattered wave are obtained inside the wedge when its angle of corner ranges from 71° to 109°. Momoi's conception (1980) of generation process of reflected and transmitted Rayleigh waves is applied to the above numerically calculated results, by which the complicated variations of reflection and transmission coefficients with wedge angle could be explained to some extent.
