“…The presence of piezoelectric components in composite materials complicates the analytical solution of the corresponding problems. Therefore, it sometimes seems necessary to apply numerical methods, as in the works of Aylikci et al [45], Ray et al [46] and in many other works listed therein, to solve the corresponding problems. However, in the present case, the exponential Fourier transform is successfully used to solve the corresponding boundary value problem in obtaining an analytical expression for the transforms of the sought values whose originals are found numerically.…”

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.

Microelectromechanical systems (MEMS) have attracted researchers' attention due to their various applications.Microplates with piezoelectric face sheets are the impending choice for MEMS. Hence, in this paper, an analysis of free vibrations of such microplates reinforced with graphene platelets resting on an elastic foundation and subjected to an external voltage in a thermal ambient is performed. The first-order shear deformation theory and a modified couple stress theory are employed to derive their kinetic and strain energies. The thermomechanical features of the core layer, reinforced with graphene platelets, are determined using the Halpin-Tsai micromechanical model. The Ritz technique is used to find the associated natural frequencies for different boundary conditions. The impact of geometry of graphene platelets, their weight fraction, temperature increment, external voltage, and boundary conditions on the outcomes are examined. The results obtained showed that decrement of the fundamental natural frequency of the microplates depends on the increment of temperature.

В [8] изучали расслоение пьезоэлектрических сандвич-пластин с краевыми трещинами при потере устойчивости. В [9] исследовали потерю устойчивости функционально-градиентных пластин при нагрузке, линейно изменяющейся в плоскости.…”

Выполнен анализ свободных колебаний микропластин, армированных пластинками графена, опирающихся на упругое основание и подверженных электрическому напряжению в условиях термической окружающей среды. Для вычисления их кинетической энергии и энергии деформирования использовали теорию сдвигового деформирования первого порядка и модифицированную теорию моментных напряжений. Термомеханические характеристики слоя сердцевины, армированного пластинками графена, определены с помощью микромеханической модели Халпина—Цая. Для нахождения соответствующих собственных частот при разных граничных условиях использовали метод Ритца. Исследовано влияние геометрии пластинок графена, их массового содержания, приращения температуры, электрического напряжения и граничных условий на характеристики свободных колебаний. Полученные результаты показали, что декремент основной собственной частоты микропластин зависит от приращения температуры.
