摘要：

A new approach to understanding the vibratory behavior of composite piezoelectric materials is proposed. Elementary ceramic rods and the effects of their width-to-thickness (W/T) ratio is studied. A model based on a finite-element method and present some experimental results that agree well with the computed data is then developed along with plots of resonant frequencies and coupling coefficients versus W/T. These graphs are used in transducer designing. © 1990 IEEE
