“…The imperfect interface with both displacement and traction jumps was studied by Olsson et al, 23 Shindo et al, 24 Hashin, 25 and Wei et al 26 The imperfect interface between two different piezoelectric materials includes not only the jump of mechanical quantity, but also the jump of electrical quantity. [27][28][29] Wang and Sudak 30 studied the imperfect interface which is mechanically compliant and dielectrically weakly (or highly) conducting. All these investigations show that the imperfect interface has significant influence on the wave propagation.…”

Dispersive characteristics of elastic waves propagating through laminated piezoelectric phononic crystal with imperfect interfaces are studied in this paper. First, the transfer matrix method and the Bloch theorem are used to derive the dispersion equation. Next, the imperfect interfaces with the jump of mechanical quantity across interface are considered. In the spring model of imperfect interface, the tractions are continuous, but displacements are discontinuous across the interface. In the mass model of imperfect interface, displacements are continuous, but tractions are discontinuous. In the spring-mass model, both traction and displacement are discontinuous. The effect of imperfect interface is introduced by inserting an additional interface transfer matrix in the calculation of total transfer matrix. Finally, the dispersion equation is solved numerically and the dispersive curves are shown in the Brillouin zone. Band gaps of phononic crystal with imperfect interface are compared with that of phononic crystal with perfect interface. The influences of the imperfect interface on the dispersive curves and the band gaps of periodic laminated piezoelectric composite are discussed.

“…Comprehensive analyses of imperfect interfaces are presented in two review articles (Wang et al, 2000;Peter, 1992). Specifically, the shear-lag model (Cheng et al, 1997;Handge, 2002), which is the simplest description (treating the interface bonding as a layer without thickness but with elasticity and interface elastic strain energy), has been widely applied to study imperfect interfaces both theoretically (Fan et al, 2006;Li and Lee, 2010;Melkumyan and Mai, 2008) and experimentally (Jin et al, 2005;Lavrentyev and Rokhlin, 1998). However, most studies have mainly focused on elastic imperfect interfaces, and only a few have been carried out to investigate the effect of imperfect viscoelastic interfaces, which are, in fact, more realistic.…”

A finite elastic plate, partially covered by piezoelectric patches on two sides to periodically charge or recharge electronic devices operating in a sealed armor, is considered to study the effects of a viscoelastic interface on the resonant frequency, transformation ratio, efficiency, displacement and stress distributions of the structure. Based on the shearslip model, we apply the Fourier series method to analyze the symmetric thickness-twist modes of the system containing an imperfect viscoelastic interface. An examination of the numerical results confirms the good convergence and high precision of the Fourier series method. If an appropriate thickness ratio is chosen, the energy-trapping phenomenon is well presented. The numerical results also reveal that the transformation ratio, efficiency and displacement of the system decrease for weaker interfaces, whereas the resonant frequency is not sensitive to interface damping parameters. This result could provide a theoretical guide to design high-performance piezoelectric plate transformers.

“…Under harsh in situ conditions, the interface in PE/PM structures may be damaged mechanically, electrically or magnetically. The effects of an imperfect interface on the propagation behavior of SH wave in PE or PE/PM structures have been discussed [2][3][4]. In addition, based on the works in [5], the mechanical model for a cylindrical PE/PM composite with imperfect interface has been presented in [2], and the dispersion behavior of the SH waves propagation has also been analyzed for the electrically open and magnetically shorted case and the electrically shorted and magnetically open case.…”

wave propagation in a cylindrically layered magneto-electric-elastic composite consisting of a piezoelectric layer and a piezomagnetic central cylinder. Based on the spring-type relation, the imperfectly bonded interface is assumed to be damaged mechanically, magnetically and/or electrically. The magneto-electrically open and shorted conditions at the free surface are taken to solve the problem. The dispersion relations of SH wave can be derived and the phase velocity are obtained numerically. Our results show that the mechanical imperfection may remarkably reduce the phase velocity under certain circumstances. However, the magneto-electrical imperfection has no obvious effect on the phase velocity in any cases. These findings are useful for the design of resonators and other microwave devices.
