Influence of a Non-Rigid Connection on the Scattering Properties of a Cylindrical Inclusion

Abbakumov, K. E., Ee, B. Ch.

Abstract. The incidence of a plane wave on a cylindrical inclusion located in a semi-infinite solid space with an inhomogeneous distribution of the rigidity at the boundary between inclusion-enclosing medium is considered. The cylindrical inclusion model is given. The solution is solved by the finite element method. Scattering indicatrices are given for different angles of incidence of a plane longitudinal wave. A significant effect of the coupling stiffness on the amplitude of the scattered field is shown.
