**Excitation of Shear
Waves in a Piezoceramic Half-space with Two Tunnel Holes by System of Surface
Electrodes**

An antiplane mixed dynamic problem of
electroelasticity for a piezoceramic half-space weakened by two tunnel holes is
considered. Excitation of electroelastic fields occurs due to the effect of the
given electrodes electric potential differences.

The boundary problem is reduced to a system of singular
integro-differential equations with discontinuous kernels which is realized by
the quadrature method. Results of parametric investigations characterizing the
behavior of the components of electroelastic field on the boundary and in the
area of a piecewise-homogeneous half-space are given.
