Compelled axysimmetric flexural fluctuations of thick round rigid piezoceramic plate

New closed solution of axisymmetric nonstationary problem of the theory of electroelasticity for thick round piezoceramic plate with rigid of its external radial surface is constructed. Calculated relations are obtained by method of expansion in eigen vector functions in the form of structural algorithm of finite transformations. Numerical results allow to define the natural-vibration frequency, the stress-strain state of the testing element, and also the potential and intensity of the induced electric field.
