    Effect of porosity and gradation of Galfenol-D on vibration suppression of bidirectional functionally graded beam
    (Elsevier Ltd, 2022) Patil, M.A.; Kadoli, R.
    A differential quadrature technique is used to investigate the vibration control response of bidirectional functionally graded imperfect aluminium-Terfenol-D and aluminium-Galfenol-D. In both transverse and axial orientations, the Terfenol-D and Galfenol-D materials are functionally graded. The bidirectional FG imperfect aluminium-Terfenol-D and aluminium-Galfenol-D governing equation is based on generalised beam theory. With consideration of uniform and uneven porosity distribution, the influence of porosity and an externally applied magnetic field on free vibration suppression behaviour is recorded. In terms of damping performance, Galfenol-D exceeds Terfenol-D. The effect of Lorentz force on the fundamental frequencies is discussed. It's worth noting that the overdamping response of the aluminium-Galfenol-D beam takes less than 0.1 s, but the exponential decay of the aluminium-Terfenol-D beam takes just 0.9 s. © 2022

    Terfenol-D Composite Actuator For Vibration Suppression Applications: A Review
    (Springer Science and Business Media Deutschland GmbH, 2023) Patil, M.A.; Kadoli, R.
    Terfenol-D can be employed as a sensor and/or actuator in applications such as vibration control, noise reduction, health monitoring and energy harvesting. Several scholars have paid significant attention in the previous research to theoretical modelling and formulation for free and force vibration of laminated composite beams/plates. The free vibration control of beams and plates that have been combined with a Terfenol-D layer is the only topic of this review paper. This article discusses the potential scope for future study on laminated composite beams and plates combined with Terfenol-D layer. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
