Abstract

The diffraction of time-harmonic, vertically polarized, plane elastic waves by a rigid strip is investigated with the aid of the integral-equation method. Using the integral representation for the particle displacement of the scattered wave, it is shown that the resulting integral equations of the first kind uncouple for this kind of obstacle. In them, the amounts by which the shearing stress and the tensile stress jump across the strip occur as unknown quantities. The integral equations are solved numerically. Normalized power scattering characteristics and scattering cross-sections are computed.
