The propagation of shear horizontal waves in a porous piezoelectric composite structure is investigated analytically in this paper. A two-layer structure comprised of perfectly bonded piezoelectric layers is considered. The solution of mechanical displacement and electrical potential is found by solving the constitutive equation for a porous piezoelectric composite structure. Then the dispersion relation is derived for the wave propagation along the direction normal to layering and in the direction of layering. The results obtained from the investigation show the dependence of the wave number on the thickness of the alternative layer in piezoelectric material. Also the phase velocity has been significantly influenced by the variation of elastic constant and porosity. The results provide a theoretical framework for designing and development of underwater acoustic devices for sensing and nondestructive testing.

“…They applied the state space technique of solving the differential equations to obtain the dispersion equation related with the considered model of their problem. Moreover, Li and Jin (2015) examined the propagation phenomenon of SH-waves electrified with the aid of an external voltage source through a piezoelectric stratum imperfectly connected to a metallic half-space.…”

Purpose This mathematical analysis has been accomplished for the purpose of understanding the propagation behaviour like phase velocity and attenuation of Love-type waves through visco-micropolar composite Earth’s structure. Design/methodology/approach The considered geometry of this problem involves a micropolar Voigt-type viscoelastic stratum imperfectly bonded to a heterogeneous Voigt-type viscoelastic substratum. With the aid of governing equations of motion of each individual medium and method of separation of variable, the components of micro-rotation and displacement have been obtained. Findings The boundary conditions of the presumed geometry at the free surface and at the interface, together with the obtained components of micro-rotation, displacement and mechanical stresses give rise to the determinant form of the dispersion relation. Moreover, some noteworthy cases have also been extrapolated in detail. Graphical interpretation irradiating the impact of viscoelasticity, micropolarity, heterogeneity and imperfectness on the phase velocity and attenuation of Love-type waves is the principal highlight of the present study. Practical implications In this study, the influence of the considered parameters such as micropolarity, viscoelasticity, heterogeneity, and imperfectness has been elucidated graphically on the phase velocity and attenuation of Love-type waves. It has been noticed from the graphs that with the rising magnitude of micropolarity and heterogeneity, the attenuation curves shift upwards, that is the loss of energy of these waves takes place in a rapid way. Hence, from the outcomes of the present analysis, it can be concluded that heterogeneous micropolar stratified media can serve as a helpful tool in increasing the attenuation or in other words, loss of energy of Love-type waves, thus reducing the devastating behaviour of these waves. Originality/value Till date, the mathematical modelling as well as vibrational analysis of Love-type waves in a viscoelastic substrate overloaded by visco-micropolar composite Earth’s structure with mechanical interfacial imperfection remain unattempted by researchers round the globe. The current analysis is an approach for studying the traversal traits of surface waves (here, Love-type waves) in a realistic stratified model of the Earth’s crust and may thus, serves as a dynamic paraphernalia in various domains like earthquake and geotechnical engineering; exploration geology and soil mechanics and many more, both in a conceptual as well as pragmatic manner.

“…Keeping this in mind, it is required to consider the imperfectness lying between the interfaces of the structures, because in any engineering analysis and design of structures, there is a significant impact of imperfection of the interface. Numerous eminent researchers have developed analytical models of imperfect bonding in their study (Chaudhary et al, 2018;Guo et al, 2015;Li and Jin, 2014;Liu et al, 2007;Wei et al, 2016). The solutions for scattering of antiplane shear waves by a piezoelectric structure with an imperfect interface are analysed by Wang et al (2007).…”

The primary objective of this article is to investigate the behaviour of horizontally polarized shear (SH) wave propagation in piezoelectric composite structure consisting of functionally graded piezoelectric material layer imperfectly bonded to functionally graded porous piezoelectric material half-space. The linear form of functional gradedness varying continuously along with depth is considered in both functionally graded piezoelectric material layer and functionally graded porous piezoelectric material half-space. The interface of the composite structure is considered to be damaged mechanically and/or electrically. Wentzel–Kramers–Brillouin asymptotic approach is adopted to solve the coupled electromechanical field differential equations of both functionally graded piezoelectric material layer and functionally graded porous piezoelectric material half-space. An analytical treatment has been employed to determine the dispersion relations of propagating SH-wave for both electrically short and electrically open conditions, which further reduced to the pre-established and classical results as special case of the problem. The effect of various affecting parameters, namely, functional gradedness, wave number, mechanical/electrical imperfection parameters in the presence and absence of porosity on the phase velocity of SH-wave, has been reported through numerical computation and graphical demonstration. In addition, the variation of the coupled electromechanical factor with dimensionless wave number and cut-off frequency with different modes of propagation of wave for electrically short and electrically open cases has also been discussed.
