“…Their results show that mechanical displacement and phase velocity are greatly effected by the biasing electric and magnetic fields. In 2016, Ezzin et al [18] discussed the influence of material properties on phase velocity and analyzed the dispersion characteristic, through examining the Love waves propagating in a piezoelectric material layer on a piezomagnetic half-space.…”

The complex Rayleigh waves play an important role in the energy conversion efficiency of magneto-electro-elastic devices, so it is necessary to explore the wave propagation characteristics for the better applications in engineering. This paper modifies the Laguerre orthogonal polynomial to investigate the complex Rayleigh waves propagating in nonhomogeneous magneto-electro-elastic half-spaces. The improved method simplifies the calculation process by incorporating boundary conditions into the constitutive relations, shortens the solving time by transforming the solution of wave equation to an eigenvalue problem, and obtains all wave modes, including real and imaginary and complex wavenumbers. The three-dimensional curves of full frequency spectrum and phase velocities are presented for the better description of the conversion from complex Rayleigh wave modes to real wave ones; besides, the displacement distributions, electric and magnetic potential curves are obtained in thickness and propagation directions, respectively. Numerical results are analyzed and discussed elaborately in three cases: variation of nonhomogeneous coefficients, absence of magnetism, and absence of electricity. The results can be used to optimize and fabricate the acoustic surface wave devices of the nonhomogeneous magneto-electro-elastic materials.

“…Recently, much attention was paid to the investigation of the effect of initial stress on Love wave behavior in piezoelectric structures [ 7 , 17 , 18 ], magnetoelectroelastic continua [ 19 ], porous media [ 20 ], and granular materials [ 21 ]. The propagation of Love waves in polarized ceramics using equations of linear piezoelectromagnetism was discussed in [ 19 , 22 , 23 ].…”

The non-classical linear governing equations of strain gradient piezoelectricity with micro-inertia effect are used to investigate Love wave propagation in a layered piezoelectric structure. The influence of flexoelectricity and micro-inertia effect on the phase wave velocity in a thin homogeneous flexoelectric layer deposited on a piezoelectric substrate is investigated. The dispersion relation for Love waves is obtained. The phase velocity is numerically calculated and graphically illustrated for the electric open-circuit and short-circuit conditions and for distinct material properties of the layer and substrate. The influence of direct flexoelectricity, micro-inertia effect, as well as the layer thickness on Love wave propagation is studied individually. It is found that flexoelectricity increases the Love-wave phase velocity, while the micro-inertia effect reduces its value. These effects become more significant for Love waves with shorter wavelengths and small guiding layer thicknesses.

“…Application of rotation is being discussed by many academicians (Fang et al, 2002; Sharma et al, 2008; Sharma and Walia, 2007) using wave transference through piezoelectric material. Simultaneously, the effects and applications of stress and strain analysis theory on mechanical structures and engineering composites are not ignorable and which are well introduced in Ferreira et al (2005, 2006), Sofiyev et al (2017), Hui (1988), Ezzin et al (2016), Dahmen et al (2016) and Kolahchi et al (2017). Nasedkin and Eremeyev (2014) investigate the harmonic vibrations of nanosized piezoelectric bodies with surface effects.…”

An analytical approach is adopted to investigate the SH waves in a composite structure consisting of initially stressed rotating piezoelectric layer and initially stressed substrate with rotation. The interface between the layer and the substrate is assumed to be imperfect. Two distinct types of imperfect interfaces (dielectrically weakly and highly conducting) are considered. Secular equations have been obtained for both electrically open and short cases with weakly and highly performing interface. Particular cases have been derived and matched with existing result. The characteristics of SH wave through the considered framework and their state of relying on different physical and geometrical parameters have been scrutinized based on their numerical results. The parallel simulated outcomes of disparate physical quantities, namely, phase velocity, group velocity, dispersive curves, initial stress, rotation and electromechanical coupling factor, and stress distribution of SH wave in the considered structure are investigated. The considered model may be useful in theoretical foundation and practical application for the development of piezoelectric sensors, structural health monitoring, and surface acoustic wave devices.
