Wave propagation control in piezoelectric meta-materials has been extensively investigated in recent years due to its significant effects on elastic wave attenuation. In this work, a novel piezoelectric meta-material rod connected to three configurations of shunting circuits is proposed for broad band gaps. The numerical model is constructed to predict the band gap, attenuation constant, and vibration transmission. For larger attenuation within the band gaps, the shunting circuit parameters are optimized with a genetic algorithm. The result shows that the structure with the optimized parameters provides prominent vibration control ability. Both the attenuation constant and the width of the band gaps are enlarged.

“…The stiffness and inertia of the periodic structures can be manipulated through some special techniques so that the band-gap locations and widths can be adjusted. The intelligent materials embedded in the periodic structures have been used to realize the adjustable band-gap performance (Chen et al, 2016; Zhu et al, 2016). The active control technology has also been employed to perform the adjustment of the band-gap performance of the periodic structures (Allam et al, 2016; Nouh et al, 2016).…”

“…It was found that the hybridization band-gaps in the sub-wavelength regime would be created due to the electromechanical coupling effects. Recently, the periodic arrays of shunted piezoelectric patches were used to control the vibration behavior and sound radiation in the low frequency range for the sandwich structures (Chen et al, 2016; Zhang et al, 2018). The wave propagation characteristics in piezoelectric phononic crystals were studied, and it was found that the active waveguide could be realized in a stop-band frequency range of a phononic crystal if piezoelectric inclusions in the phononic crystal were electrically controlled (Oh et al, 2011).…”

A novel strategy is proposed to investigate the vibration band-gap and active tuning characteristics of the laminated composite metamaterial beams. The piezoelectric actuator/sensor pairs are periodically placed along the laminated composite beam axis so that the vibration frequency band-gap and active tuning characteristics can be induced. The dynamic equations of the laminated composite metamaterial beams bonded by the piezoelectric actuator/sensor pairs are established based on the Euler–Bernoulli beam theory. The negative proportional feedback control strategy is employed to provide the positive active control stiffness for the piezoelectric actuator/sensor patches. The spectral element method is used to calculate the dynamic responses of the laminated composite metamaterial beams with the periodically placed piezoelectric patches, and the calculation accuracy for the dynamic responses is validated by the finite element method. The results demonstrating the high-performance vibration band-gap properties in the low-frequency ranges can be achieved by properly designing the sizes and the number of the piezoelectric patches. Moreover, the vibration band-gap characteristics, especially the band-gap width and the normalized band-gap width with respect to the considered excitation frequency range, can be significantly changed by tuning the structural parameters of the piezoelectric actuators and sensors. In addition, the cross-ply angle of the laminated composite metamaterial beams has significant influences on the band-gap characteristics and the vibration reduction performance of the laminated composite beam structures.

“…Consequently, the design of low-frequency band gaps in elastic metamaterials becomes physically easy to achieve by tuning the local resonators. Due to this fact, the application of elastic metamaterials for low-frequency vibration suppression has attracted numerous research interests in recent years (Banerjee et al, 2017;Chen et al, 2016;Cheng et al, 2013;Cheng and Shi, 2014;Hu et al, 2017b;Li et al, 2018;Liu et al, 2007;Zhu et al, 2014).…”

This article presents a theoretical study of a tunable metamaterial beam for low-frequency broadband vibration suppression. First, the mechanism of employing the shunt circuit technique to realize the internal coupling between two adjacent local resonators is introduced. The working principle of the proposed metamaterial beam by integrating the shunt circuit technique is demonstrated. The stability of the proposed metamaterial beam is then analysed, and the corresponding criterion is proposed. Subsequently, analytical models of the proposed metamaterial beam are developed. The band structures and the transmittances are calculated. The analytical study demonstrates the generation of multiple band gaps using a shunt negative capacitance circuit, which is equivalent to a coupling spring. A parametric study is conducted to investigate the effect of the equivalent coupling stiffness on the band gaps and the corresponding suppression regions. It is found that the band gaps are controllable by varying the equivalent coupling stiffness. Finally, to verify the analytical solutions, a finite-element model of the proposed metamaterial beam is developed. The simulation results confirm the existence of multiple band gaps, which are tunable through modification of the negative capacitance. The broadband vibration-suppression ability of the proposed metamaterial beam is thus confirmed.
