Magnetoelectric (ME) interaction in magnetostrictive-piezoelectric multiferroic structures consists in inducing the electric field across the structure in an applied magnetic field and is a product property of magnetostriction and piezoelectricity in components. ME voltage coefficient that is the ratio of induced electric field to applied magnetic field is the key parameter of ME coupling stren...

Vibration energy harvesting is a new alternative to lithium battery power for low-power devices, attempting recover wasted or lost vibration generate electricity. Magnetostrictive-based exploits the coupling properties of Villari and Faraday electromagnetic induction effects achieve mechanical–magnetic–electric conversion. In order better apply actual environment, such as buses, improve ability...

A nonlinear couple modeling of magnetostrictive cantilever is built by combining Gibb’s free energy formulation with the Euler-Bernoulli beam theory. The Gibb’s free energy corresponding to different orientations in 3D space can be expressed in terms of their direction cosines, the stress at a given point can be described by classical theory. The magnetomechanical bending experimental setup is ...

The study of magnetostrictive material in laminated plate under thermal vibration is calculated by using the generalized differential quadrature (GDQ) method. The YNS shear deformation effect is included in the time dependent of displacement field. In the thermoelastic stress-strain relations that containing the linear temperature rise and the magnetostrictive coupling terms with velocity feedb...

Acoustic wave devices have gained enormous interest for sensor applications. In the current practice, the surface acoustic waves are usually generated and measured by piezoelectric transducers. In this work, however, we propose to generate the acoustic waves by using a magnetostrictive transducer using magneticstrictive nickel strip gratings and a sensing coil. The coil encircling the gratings ...

Techniques for modeling hysteresis and material nonlinearities in magnetostrictive materials are presented. Hys-teresis in these materials is due to both the driving magnetic eld and stress relations within the material and is signiicant throughout most of the drive range of the material. Two characterizations are presented here. The rst model is posed in terms of Preisach operators and is pure...

The paper proposes a two-stage model able to describe the dynamic behavior of a commercial magnetostrictive actuator in the frequency range of interest for fast actuation purposes. The first stage is a static model of hysteresis, while the second one is a linear dynamic model. The model structure allows to define well-assessed identification procedures for both stages. In particular, the identi...

Ni-Fe alloy/ZnO nanorod composites were fabricated and the magnetoelectric effect was demonstrated. The ZnO and Ni-Fe alloy serve as the piezoelectric phase and the magnetostrictive phase in the nanocomposite, respectively. Since the nanorod structure possesses the inherent nature of a large surface-to-volume ratio, it greatly enhances the interplay between the piezoelectric and magnetostrictiv...
