The grounds of a new computational-experimental iterative methodology that makes it possible to determine electromechanical coupling coefficients and parameters of the energy loss with high precision are described by the example of famous problems of the longitudinal vibrations of a thin piezoceramic rod with transverse polarization and radial oscillations of a thin circular piezoceramic plate with unbroken electrodes.

Keywords: computational-experimental iterative methodology, loss energy factors, piezoceramic bar resonator
