| Abstract |
This study analytically examines the influence of the flexoelectric effect on shear-horizontal (SH) wave propagation in a layered structure composed of a piezo-flexoelectric layer bonded to a
piezo-flexoelectric substrate, considering an imperfect interface. By applying appropriate boundary
and interfacial conditions, a frequency equation is derived that relates the phase velocity to the wave
number, incorporating the effects of material properties, interface conditions, geometric dimensions,
and flexoelectric coupling. The resulting dispersion relation highlights the roles of interface imperfection, flexoelectric strength, and structural configuration. Numerical simulations performed using
Mathematica software illustrate the dispersion behaviour under electrically open and short-circuited
boundary conditions, offering insights into the electromechanical wave interaction in layered piezoflexoelectric media. These findings offer new insights into the design and analysis of piezo-flexoelectric devices with realistic interface conditions. |
