Remote determination of mechanical parameters of thin flat inclusions of low contrast

We propose an algorithm for the remote determination of physicomechanical parameters of thin flat spatial elastic inclusions of variable thickness. We also establish the orientation of inclusions in an elastic matrix. The difference between the mechanical properties of the inhomogeneity and the matrix is insignificant as compared with the small thickness of an inclusion. The defect is sounded by elastic longitudinal waves, and the required parameters are determined from the amplitudes of scattering of these waves to the Fraunhofer zone.
