“…Flexible magnetostrictive actuators have been developed by embedding magnetostrictive particles into resins. Murtyet al [62] created a laminated composite beam that contains a Terfenol-D particle embedded layer. Zhou and Zhou [63] later implemented a negative velocity feedback controller together with an analytical nonlinear constitutive model to mitigate the composite beam vibrations.…”

Excessive vibrations in civil and mechanical systems can cause structural damage or detrimental noise. Structural vibrations can be mitigated either by attenuating energy from vibration sources or isolating external disturbance from target structures. Magnetostrictive materials coupling mechanical and magnetic energies have provided innovative solutions to vibration control challenges. Depending on the system's tunability and power consumption, the existing vibration control strategies are categorized into active, passive, and semi-active types. This article first summarizes the unique properties of magnetostrictive materials that lead to compact and reliable vibration control strategies. Several magnetostrictive vibration control mechanisms together with their performance are then studied using lumped parameter models. Finally, this article reviews the current state of vibration control applications utilizing magnetostrictive materials, especially Terfenol-D and Galfenol.

In this research, dynamic response of tapered plate made of MsM (magnetostrictive material) is studied for the rst time. First-order Shear Deformation Theory (FSDT) is used to derive the governing equations of tapered MsP (magnetostrictive plate) while the thickness varies linearly. To enhance accuracy of the results, shear correction factor is considered and a feedback control system is utilized to investigate the e ects of magnetic eld on MsP. The ve equations of motion that are obtained by Hamilton's principle are solved using Di erential Quadrature Method (DQM) and compared with those available in the literature. Results indicate the e ect of various parameters such as aspect ratio, thickness ratio, taper ratio, boundary conditions, and the controller e ect of velocity feedback gain on the frequency of MsP. These ndings can be used for active noise and vibration cancellation systems in many smart structures.

“…It also has high energy density, negligible weight, and point excitation with a wide frequency bandwidth [7][8][9]. Considerable effort is spent to understand the interaction between magnetostrictive layers and structural laminated composites and the feasibility of using magnetostrictive materials for active vibration/deflection suppressions in beam and plate structures [10][11][12][13][14][15][16][17][18].…”
