Knowledge of natural frequency of pipeline conveying fluid has relevance to designer to avoid failure of pipeline due to resonance. The damping characteristics of pipe material can be increased by using smart materials like magnetostrictive namely, TERFENOL-D. The objective of the present chapter is to investigate vibration and instability characteristics of functionally graded Terfenol-D layered fluid conveying pipe utilizing Terfenol-D layer as an actuator. First, the divergence of fluid conveying pipe is investigated without feedback control gain and thermal loading. Subsequently, the eigenvalue diagrams are studied to examine methodically the vibrational characteristics and possible flutter and bifurcation instabilities eventuate in different vibrational modes. Actuation of Terfenol-D layer shows improved stability condition of fluid conveying pipe with variation in feedback control gain and thermal loading. Differential quadrature and differential transform procedures are used to solve equation of motion of the problem derived based on Euler-Bernoulli beam theory. Finally, the effects of important parameters including the feedback control gain, thermal loading, inner radius of pipe and density of fluid on vibration behavior of fluid conveying pipe, are explored and presented in numerical results.

“…Study on bending behavior of sandwich nanoplate with integrated piezomagnetic face-sheets has been dealt in (Arefi and Zenkour, 2017) using Kirchhoff's plate model. Moreover, vibrational analysis of FG-CNT reinforced sandwich beams embedded with magneto-strictive actuators has been examined by Talebitooti and Fadaee (2019) and they conclude that CNT volume fraction, their distribution and angular velocity have an impact on vibration suppression in various modes of the sandwich beam. In another work, Dat et al (2020) proposed an analytical approach to study the magneto-electro-elastic vibration of intelligent nano-reinforced sandwich plate.…”

The application of piezomagnetic layers on the external surfaces of passive sandwich shells has the potential to create multifunctional smart sandwich structures. This work introduces new smart magneto–electro–elastic (MEE) shells and studies its geometrically nonlinear bending and transient behavior as a first endeavor. A High-order Shear Deformation Theory (HSDT) is adopted to develop the Finite Element model of the smart MEE shells considering the multiphysics couplings, meanwhile the Lagrangian nonlinear strain-displacement relations are employed to account the geometric nonlinearity. The developed FE is modeled with nodal degrees of freedom that include displacements, rotations, electric and magnetic potentials. Moreover, the physical characteristics of aggregated CNTRC are evaluated based on micromechanics model incorporating the two agglomeration parameters. Different agglomeration schemas are considered for CNTs in nanocomposite core layer. The precision and reliability of the current FE model are confirmed through a comparison of the existing results in the open literature. The study explores the influence of parameters such CNT volume fraction and their agglomeration phenomena and various geometrical parameters of the shell on the nonlinear bending and dynamic behavior of smart MEE sandwich structures. The findings provide valuable insights into the subject.

The general vibration control strategy of beam structures is a global vibration control method based on the principle of modal superposition. However, the vibration wave control of beams can achieve local control of the vibration energy. This paper presents a wave control method for the local vibration control of fractional viscoelastic composite beams based on the operating principle of a piezoelectric sheet. To obtain better control performance, a particle swarm optimization algorithm was adopted to optimize the parameters of the piezoelectric sheet. A linear quadratic regulator control algorithm was designed to verify the validity of the proposed method. In addition, the effects of the piezoelectric sheet number and fractional order on the amplitude response and optimization parameters were investigated. We observed that the proposed method has a good control effect on the local area vibration, and it can control the flow direction of the vibration power. The proposed method can be used to directly design the voltage and phase of a piezoelectric sheet without real-time feedback computation. This method is suitable for reducing local vibration under single repetitive operating conditions in engineering and can provide a theoretical basis for a follow-up study on the acoustic black hole phenomenon.
