BLEUSTEIN-GULYAEV WAVES IN A FUNCTIONALLY GRADED PIEZOELECTRIC MATERIAL (FGPM) LAYERED SYSTEM
Propagation behavior of Bleustein-Gulyaev waves (electro-acoustic waves) in afunctionally graded piezoelectric layer/transversely isotropic piezoelectric substratelayered system is taken into account.Influences of graded variation of functionallygraded piezoelectric materials (FGPMs) coefficients on dispersion relations ofBleustein-Gulyaev waves are discussed.It is revealed that for a certain rangefrequency of Bleustein-Gulyaev waves propagating in the FGPM layered system,the mechanical perturbations of the particles are only restricted in the layer and thephase velocity is independent of the electrical boundary conditions at the freesurface.Relationship between the frequency and the graded variation of materialparameters can provide theoretical basis for the characterization of FGPM gradedvariation patterns.
