Determination of Mechanical Parameters of a Disk-Shaped Non-Contrast Inclusion in an Elastic Matrix Using Torsion Wave Monitoring Data

The direct problem of scattering of torsion waves by thin elastic (in particular piezoelectric) disk-shaped inclusions of low contrast has been investigated. Analytical expressions for the wave fields of displacements in an elastic medium were obtained. An effective algorithm for determining the mechanical parameters of such inclusions from the data of scattering of waves into the far zone is proposed.
