Anatomy of flexoelectricity in micro plates with dielectrically highly/weakly and mechanically complaint interface

Abstract

The present study analytically investigates the Love-type wave vibrations in a piezoelectric thin film with highly and weakly dielectric conducting interface with pre-stressed elastic plate. Dispersion equations are obtained analytically for both electrically open and short cases together with highly and weekly interfaces in the transcendental complex form. Outcomes specify that microstructures consisting flexoelectricity has an essential influence on dispersion features of the Love-type wave and also affected by the conducting interface. As a remarkable outcome, complex phase velocity with positive imaginary part increases with time. Moreover, the dispersion relation depends substantially on the flexoelectric coefficients and width of the guiding plate. The present study is the prior attempt to show the flexoelectricity influence with weekly and highly conducting interfaces.
