Description

For diagnostic acoustic methods piezoelectric ceramic circular disks are typically used as active transducer elements. To calculate the response of such transducers, simplified numerical calculation methods, having limited applicability, are widely used. In the present work the strict analytical methods of elasticity theory have been used to calculate the three-dimensional vibrations of circular piezoelectric disks having a general dependence on both diameter and thickness. The approach we employed is based on the eigenfunction method of dynamic electric elasticity developed in [1].

Analytical Approach to the Calculation of Three-Dimensional Transducers for the Acoustic Control Methods
