Abstract
The diffraction of two-dimensional elastic waves by a cylindrical obstacle is investigated. In two-dimensional wave motions, the geometrical configuration as well as the field quantities involved are assumed to be independent of one of the Cartesian coordinates. As such, the two-dimensional theory can be considered as a special case of the three-dimensional one. Following this line of reasoning, the integral-equation formulation of two-dimensional elastodynamic diffraction problems is derived. For a number of configurations, the resulting integral equations are solved numerically. Also, numerical results pertaining to normalized power scattering characteristics and extinction cross-sections are presented.
