“…Tang et al [18] analyzed the influences of interfacial phase and constituent properties on magnetostriction using an asymptotic homogenization approach. Zhong et al [19] constructed a micromechanical model based on the variation asymptotic homogenization method, and obtained local stress field and magnetic flux density. Based on Eshelby equivalent inclusion and Mori Tanaka method, Xue [20] and Guan [21] predicted the effective magnetostrictive strain of particle reinforced composites.…”

“…Recently, Yu and Zhong [26][27][28][29] put forward a new multiscale modeling technique to deal with dimensionality-reducing structures based on the variational asymptotic method (VAM) [30]. With this method, the small structural parameters (such as the thicknesswidth ratio) were used to asymptotically expand the energy functional, and the higherorder terms were removed to obtain the approximate energy of different orders and the corresponding dimension reduction model, which achieved a good tradeoff between accuracy and effectiveness.…”

The orthogrid-stiffened FRP panel (OSFP) is a generic structural element in weight-sensitive structure applications. Based on the variational asymptotic method, a 2D reduced-order plate model (2D-RPM) of OSFP was constructed through matching the strain energy of the original panel for static and dynamic analyses. The local field distributions were recovered using the recovery relationship and global response. The relative influences of select parameters on the effective performance of the OSFP were revealed by parametric studies. The comparative results showed that the effective performance of the OSFP predicted by the 2D-RPM were consistent with those predicted by the 3D finite element model, but the computational efficiency was greatly improved. The stiffener height had the greatest influence on the natural frequency of the panel. The layup configurations of laminates had significant influences on the equivalent stiffness and buckling load of the OSFP but had little effect on the vibration modes, which could be varied by adjusting the stiffening forms.

“…Magnetostrictive materials (MsMs) such as Terfenol-D can provide large strain and quick response; also, are widely used in sensors, actuators, etc. In spite of, their weight, disadvantage of shape control, and acoustic impedance, magnetostrictive composite materials are usually a better technical solution in the case of many applications such as ultrasonic generators, ultrasonic receivers, and echo detectors; also, magnetostrictive composites are developed by combining MsMs with passive materials to form a variety of types of magnetostrictive composite systems [4,5].…”

In the present study, free vibration of magnetostrictive sandwich composite micro plate with magnetostrictive core and composite face sheets are investigated. The modified couple stress theory is taken into account so as to consider the small scale effects. The surrounding elastic medium is simulated as visco-Pasternak foundation to study the effects of both damping and shear effects. Using energy method, Hamilton’s principle and first-order shear deformation theory, the governing equations of motion and related boundary conditions are obtained. Finally, the differential quadrature method is employed to analysis the vibration of magnetostrictive sandwich composite micro plate. In this regard, the dimensionless frequency are plotted to study the effects of small scale parameter, surrounding elastic medium, magnetic field, composite fiber angle, aspect ratio, thickness ratio, and boundary conditions. The results indicate that the magnetic field and composite fiber angle play a key role in the dimensionless frequency of magnetostrictive sandwich composite micro plate. The obtained results in this article can be used to design sensors and actuators, aerospace industry, and control of vibration response of systems.
