Paper Abstract

`Electromechanical bending effect' of thin homogeneous piezoceramic plate in consequence of an uneven thickness polarization is investigated. The distribution of electrical field strength and polarization is determined taking into account the injection of electrons from the cathode. Theoretical and experimental data are compared. Formulas for calculation of the mechanical stresses, strains and electrical field strength in piezoceramic plates and shells are obtained. Engineering method and results of numerical calculation of deflection of a cantilever homogeneous piezoelectric plate are given. The comparison of the calculated and experimental determined deflection of the free end of a cantilever piezoceramic plate can be used for the estimation of the real polarization, which arises in the making of thin piezoelectric samples.
