Description
Summary:It is presented numerical-analytical technique for solving boundary-value problems concerned the diffractional elastic waves scattering on tunnel cylindrical cavities. The cavities are partially tight by inclusions of radial cross-section. The technique is based on the wave field expressions for general body. The calculations were carried out when the inclusion occupies both left-hand and right-hand cavity's side. During the investigation the relative wavelength and the physical specifications as well as the size of inclusion were changed.
