“…The aforementioned works serve not only their direct purpose but also provide the theoretical basis for the study of the corresponding problems related to the cases in which the plate material is intelligent, such as piezoelectric or piezomagnetic. It should be noted that the results of such investigations have great importance for energy harvesting procedures (see, for example, references [15][16][17][18] and others listed therein), and in hydroacoustic transducers that receive (or generate) acoustic waves (see, for example references [19][20][21] and others listed therein).…”

The present work investigates the mechanically forced vibration of the hydro-elasto-piezoelectric system consisting of a two-layer plate "elastic+PZT", a compressible viscous fluid, and a rigid wall. It is assumed that the PZT (piezoelectric) layer of the plate is in contact with the fluid and time-harmonic linear forces act on the free surface of the elastic-metallic layer. This study is valuable because it considers for the first time the mechanical vibration of the metal+piezoelectric bilayer plate in contact with a fluid. It is also the first time that the influence of the volumetric concentration of the constituents on the vibration of the hydro-elasto-piezoelectric system is studied. Another value of the present work is the use of the exact equations and relations of elasto-electrodynamics for elastic and piezoelectric materials to describe the motion of the plate layers within the framework of the piecewise homogeneous body model and the use of the linearized Navier-Stokes equations to describe the flow of the compressible viscous fluid. The plane-strain state in the plate and the plane flow in the fluid take place. For the solution of the corresponding boundary-value problem, the Fourier transform is used with respect to the spatial coordinate on the axis along the laying direction of the plate. The analytical expressions of the Fourier transform of all the sought values of each component of the system are determined. The origins of the searched values are determined numerically, after which numerical results on the stress on the fluid and plate interface planes are presented and discussed. These results are obtained for the case where PZT-2 is chosen as the piezoelectric material, steel and aluminum as the elastic metal materials, and Glycerin as the fluid. Analysis of these results allows conclusions to be drawn about the character of the problem parameters on the frequency response of the interfacial stress. In particular, it was found that after a certain value of the vibration frequency, the presence of the metal layer in the two-layer plate led to an increase in the absolute values of the above interfacial stress.

“…Following the mathematical accuracy and formalism, modified Bessel’s, Whittaker function, and series expansion method are used to derive analytical solution for the torsional wave propagation. Snell’s law for reflection/refraction and transmission of waves and antisymmetric Lamb waves through the layered structure are unfolded (Kuznetsova et al, 2011; Shekhar and Parvez, 2016), respectively. Using wave theory and theory of elastodynamics, some research articles are available to study different types of wave propagation phenomenon through piezoelectric material such as Lamb waves in piezo-composite material (Ezzin et al, 2017), self-dependent nonlinear vibration following surface/interface theory (Fang and Zhu, 2017), shear waves in one-dimensional periodic piezoelectric material (Ghazaryan and Piliposyan, 2011), shear Bloch waves in periodic piezoelectric waveguides (Piliposyan et al, 2014), Love waves in electrically shorted piezoelectric nanofilm (Zhang et al, 2016), anti-plane transverse wave propagation, Rayleigh wave transmission, and nonlinear harmonic vibration through piezoelectric materials (Saadatnia and Esmailzadeh, 2017; Sahu et al, 2017; Wang et al, 2008).…”

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.

Bu çalışmada piezoelektrik plak, viskoz akışkan ve rijit duvardan oluşan bir sisteme, harmonik bir mekanik kuvvet uygulandığında ortaya çıkan titreşime viskoz akışkan özelliklerinin etkisi incelenmiştir. Plağın hareketi, doğrusallaştırılmış elektro-elastisite teorisinin kesin denklemleri ile ifade edilmiştir. Akışkan akımı ise doğrusallaştırılmış Navier-Stokes denklemleri ile yazılmıştır. Plakta düzlem şekil değiştirme durumunun olduğu, akışkanın ise düzlemsel akış yaptığı varsayılmıştır. Problemin matematiksel formülasyonunu ifade eden denklemlere, sınır ve uygunluk koşullarına, plağın uzunluğu yönündeki koordinata göre Fourier dönüşümü uygulanmıştır. Ters Fourier dönüşümü ise sayısal olarak hesaplanmıştır. İncelenen hidro-piezoelektrik sistem farklı akışkanlar için ele alınmış ve akışkanın özelliklerinin, plak ve akışkan ara yüzeyindeki basınç değeri üzerindeki etkisi araştırılmıştır. Sonuçlar tartışılmış ve akışkanın viskozitesinin artmasının, ara yüzeydeki basıncı mutlak değerce arttırdığı gözlemlenmiştir. Bu araştırmanın, özellikle farklı mühendislik alanlarında yapılan enerji hasadı çalışmalarına katkıda bulunması amaçlanmıştır.
