Abstract
The diffraction of a plane electro-elastic shear wave in the piezoelectric space with a semi-infinite crack between half-spaces is considered, when an electrically conductive metallic thin layer is glued together at the interface of the half-spaces. The problem is reduced to solving a Riemann-type problem on the real axis in the theory of analytic functions. The presence of a semi-infinite crack leads to the propagation of diffracted bulk and surface (localized) electro-elastic waves in piezoelectric half-spaces. We study the distribution of the wave field in half-spaces using the methods of the integral Fourier transform, the theory of functions of complex variable and contour integration.
