This paper investigates the propagation characteristics of bending edge waves in a thick piezoelectric film, taking into account the electromechanical coupling. The problem is analyzed analytically and numerically using harmonic wave propagation. The results show that an increase in voltage leads to a decrease in critical velocity, while an increase in the Winkler's constant leads to an increase in critical velocity.
This paper is concerned with the analysis of bending edge waves travelling in a thick Kirchhoff-type piezoelectric film resting on a Winkler-Fuss foundation. The electromechanical coupling is accounted for in defining flexural rigidities to embrace piezoelectric and dielectric material constants. Dynamics is solved analytically and demonstrated numerically by assuming harmonic wave propagation. It is observed that an increase of the voltage leads to a decrease of the critical velocity, while an increase of the Winkler's constant leads to an increase of the critical velocity.
