Abstract
The Fourier integral transform has been used
to reduce the diffraction problem of the normal SH-wave
on a semi-infinite rigid inclusion in the elastic layer to the
Wiener-Hopf equation. Its solution is obtained by the
factorization method. The analytical expressions of the
diffracted displacement fields have been represented in any
region of interest. The dependences of the scattered field on
the parameters of the structure have been given. The
properties of identification of the inclusion type defect in
the plane layer have been illustrated.
