Yasinska O. Scattering of bending waves on elastic heterogeneities in resilient waveguides

Dissertation is devoted for research of the wave fields at the antisymmetric vibrations of an elastic inhomogeneous waveguide .The composite waveguide was considered in this work in quality an inhomogeneous waveguide, it was formed by a strong contact of two half-layers the same thickness but with different mechanical characteristics, a stepped waveguide was formed by a strong contact with two half-layers in different thickness and with identical or different mechanical properties and near-surface crack. Was developed the method of superposition for solving mixed boundary tasks. The physical features of formation the wave fields in such waveguides was studied by basic solutions.
