“…Different vibration control strategies are used to study vortex-induced vibrations of a bridge deck [4][5][6], building structure [7][8][9][10][11][12], and other structures [13][14][15]. It is worth mentioning that scholars have carried out much research on piezoelectric-based vibration control [16][17][18][19][20][21][22][23][24][25][26].…”

The time-delayed displacement feedback control is provided to restrain the superharmonic and subharmonic response of the elastic support beams. The nonlinear equations of the controlled elastic beam are obtained with the help of the Euler–Bernoulli beam principle and time-delayed feedback control strategy. Based on Galerkin method, the discrete nonlinear time-delayed equations are derived. Using the multiscale method, the first-order approximate solutions and stability conditions of three superharmonic and 1/3 subharmonic resonance response on controlled beams are derived. The influence of time-delayed parameters and control gain are obtained. The results show that the time-delayed displacement feedback control can effectively suppress the superharmonic and subharmonic resonance response. Selecting reasonably the time-delayed quantity and control gain can avoid the resonance region and unstable multi-solutions and improve the efficiency of the vibration control. Furthermore, with the purpose of suppressing the amplitude peak and governing the resonance stability, appropriate feedback gain and time delay are derived.

“…In this research, the surface energy effect was considered, and the government equation was solved using the Rayleigh-Ritz method. 6 Zhou et al [12] implemented an accurate approach to analyze the free vibration of piezoelectric fiber-reinforced composite cylindrical shells in a thermal environment. They assumed that the composite materials were made in two ways; first, each ply had a regular distribution, and second, the reinforcements were graded functionally through the thickness direction.…”

This paper presents free vibration of the double-curved shells and panels with piezoelectric layers in a thermal environment. Vibration characteristics of elliptical, spherical, cycloidal, and toro circular shells of revolution are studied in detail. These structures are made of a based carbon nanotubes (CNTs) core and piezoelectric layers at the upper and lower surfaces. It is supposed that temperature changes linearly through the thickness direction. Reissner-Mindlin and the first order shear deformation (FSDT) theories are implemented to derive the governing equations of the considered structures. The distribution of nanotubes is assumed to be linear along the thickness direction. For solving the equation, the General Differential Quadrature (GDQ) method is implemented to investigate the dynamic behavior of the structures. Finally, the effects of the boundary conditions, the thickness of piezoelectric layers, the functional distribution of CNTs, thermal environment and kinds of the circuit (opened-circuit and closedcircuit) are analyzed. Eigenvalue system is solved to obtain natural frequencies. It is delineated that the obtained fundamental frequency by the closed -circuit is smaller than those obtained by the opened-circuit. Another interesting result is that the natural frequency is decreased by increasing temperature.

“…However, inherent brittleness, high sensitivity to cracking, and high acoustic impedance can often generate limitations in obtaining a monolithic piezoelectric material which satisfies the multiple demands of a specified application at the same time (Jain et al, 2015; Lv et al, 2015; Sakthivel and Arockiarajan, 2012; van den Ende et al, 2013). A technical solution to overcome above challenging problems and obtain more compliant material with better electromechanical characteristics is fabricating the piezoelectric composite in which the piezoelectric fibers are embedded into a polymer matrix (Dai and Ng, 2012; Kundalwal and Ray, 2016; Panda and Panda, 2015; Zhou et al, 2019). Another advantage of the piezoelectric fiber-reinforced polymer composites, over monolithic piezoelectric materials, includes larger strength/modulus-to-weight ratios.…”

This research investigates the effect of adding graphene nano-sheets (GNSs) on the elastic and piezoelectric responses of PZT-7A piezoelectric fiber/polyimide hybrid composites. The constructional feature of this hybrid composite is such that unidirectional PZT-7A fibers are embedded into the GNS-filled polyimide material. A nested micromechanical modeling strategy based on the Mori-Tanaka scheme is developed to predict the effective properties of PZT-7A/GNS/polyimide hybrid composites. Parametric studies are performed in order to examine the influences of volume fraction, agglomeration and rolling-up of GNSs, and PZT-7A volume fraction on the piezoelectric hybrid composite coefficients. The results indicate that the elastic and piezoelectric properties of PZT-7A/polyimide composites can be improved by the uniform dispersion of GNSs. However, it is observed that the formation of GNS agglomeration into the polyimide matrix has a serious negative effect on the equivalent properties of piezoelectric hybrid composites. The present predictions are also compared with other results reported in the literature. It is believed that the modeling approach and outcomes of this research may help to design these kinds of novel and highly promising piezoelectric hybrid composites.
