CHARACTERISTICS OF SH-WAVE IN NANO-PIEZOELECTRIC LAYERED STRUCTURE WITH SURFACE EFFECT
In this paper, we investigate the influence of surface effects on SH-wave propagation in a nano-piezoelectric layered structure.The dispersion relationships are figured and presented.Through changing the thickness of piezoelectric layer and elastic layer, we find that the SH-wave exhibit thickness-dependence obviously in open and short electric boundary conditions.In addition, we research the propagation characteristics of SH-wave in two electric boundary conditions through changing the surface elastic constants of the top and the bottom free surfaces and the interface.From the results, we can find that in nanoscale, the changes of the thickness of nano-piezoelectric structures and surface elastic constants have a great effect on the characteristics of SH-wave propagation.
