Abstract:The method of characteristics is used to obtain an analytical solution describing the thickness vibrations of a piezoelectric layer polarized across the thickness and subjected to a nonstationary electric potential. The features of how the vibrations are excited and propagate under electric loading are studied. The dynamic electromechanical state of the layer is analyzed. The electric and mechanical characteristics as functions of time are plotted Translated from Prikladnaya Mekhanika, Vol. 44, No. 10, pp. 23–27, October 2008.
Keywords:electroelastic vibrations  piezoelectric layer  method of characteristics  d'Alembert's formula  electric loading
