Abstract

The steady-state wave process is considered in the piezoceramic space with the tunnel cavities-holes under the plane strain conditions in the plane, paralleled to the axis of the symmetry of the material. Supposed that the cavities surfaces are free from forces and bound with vacuum (air). Monochromatic waves of the corresponding type are considered as the loading. On the basis of the well-known fundamental solution for the unbounded piezoceramic medium, which is under harmonically changing in time concentrated forces or electric charges, the integral presentations of the amplitudes of the displacements and electric potential are constructed. The corresponding two-dimensional boundary-value problem of the electro- elasticity is reduced to the system of three singular integral equations of the second kind
