“…Much research work has been done on the propagation of the transverse surface waves in such layered structures [2][3][4][5][6][7][8][9]. Due to the intrinsic brittle property of ceramic materials and the thermal mismatch between layer and substrate, however, initial stresses appear inevitably in such layered structures during the manufacture process and have significant effects on the propagation behavior of the transverse surface waves [10][11][12][13][14][15][16].…”

Effects of covering layer thickness on Love waves in functionally graded piezoelectric substrates

An analytical approach is used to investigate the effects of covering layer thickness on the propagation behavior of Love waves in functionally graded piezoelectric materials (FGPMs) covered with a dielectric layer. The piezoelectric substrate is polarized in the direction perpendicular to the wave propagation plane, and its material parameters change continuously along the thickness direction. The dispersion equations for the existence of Love waves with respect to phase velocity are obtained for electrically open and shorted cases, respectively. A detailed investigation of the effects of the covering dielectric layer thickness on dispersion curve, phase velocity, group velocity, and electromechanical coupling factor is carried out. Numerical results show that for a given FGPM, the covering dielectric layer thickness affects significantly the fundamental mode of Love waves but has only negligible effects on the high-order modes. The changes in phase velocity, group velocity, and electromechanical coupling factor due to the change of gradient coefficient of FGPMs could be approached approximately by changing the thickness of the covering dielectric layer, which imply a potential factor for designing new-type surface wave devices with FGPMs.

“…Feng et al [1] studied the Rayleigh waves in magneto-electro-elastic half planes, and Pang et al [2] discussed the Rayleigh-type waves in a transversely isotropic piezoelectric layer on a piezomagnetic half-space; Wu et al [3] studied the Lamb wave propagation in magnetoelectroelastic plates; Du [4] with his partners discussed the Love wave propagation in layered magneto-electro-elastic structures, and Liu et al [5] studied the Love waves in layered piezoelectric/piezomagnetic structures. However, all these researches concentrated on surface waves of a magneto-electro-elastic structure.…”

This is a continued work in studying the wave propagation in a magneto-electroelastic square column (MEESC). Based on the analytic dispersive equation, group velocity equation and steady-state response obtained in our previous paper 'Steady-state response of the wave propagation in a magneto-electro-elastic square column' published in CME, the dynamical behavior of MEESC was studied in this paper. The unlimited column is an open system. The transientstate response in the open system subjected by arbitrary external fields was derived when the propagating wave pursuing method was introduced.

“…Wang et al [9] and Liu et al [10] almost simultaneously showed that a transversely isotropic magneto-electro-elastic half-space adjoining a vacuum supports the propagation of SH surface waves. The dispersion characteristics of Love waves in PE/PM layered half-spaces were studied by Du et al [11] and Liu et al [12] respectively. The reflection and refraction of plane waves at the PE and PM interface was investigated by Pang et al [13] .…”

This paper is concerned with the dynamic behaviors of wave propagation in layered periodic composites consisting of piezoelectric and piezomagnetic phases. The dispersion relations of Lamb waves are derived. Dispersion curves and displacement fields are calculated with different piezoelectric volume fractions. Numerical results for BaTiO3/CoFe2O4 composites show that the dispersion curves resemble the symmetric Lamb waves in a plate. Exchange between the longitudinal (i.e. thickness) mode and coupled mode takes place at the crossover point between dispersion curves of the first two branches. With the increase of BaTiO3 volume fraction, the crossover point appears at a lower wave number and wave velocity is higher. These findings are useful for magnetoelectric transducer applications.KEY WORDS piezoelectric/piezomagnetic composite, layered periodic structure, wave, dispersion behavior
