Excitation of Shear Waves in a Piezoceramic Medium with Two Tunnel Holes by a System of Surface Electrodes

Abstract

An antiplane mixed dynamic problem of electroelasticity for an infinite piezoceramic medium weakened by two tunnel holes is considered. The conjugated fields are excited by the difference of electric potentials applied to a system of electrodes located on the surfaces of the holes. The boundary-value problem is reduced to a system of singular integrodifferential equations with discontinuous kernels, which is solved numerically by quadratures. The results of parametric investigations, characterizing the behavior of the electric field components on the boundary and in the region of the piecewise-homogeneous space, are presented.
