Bending and buckling analyses of heterogeneous annular/circular micro sandwich plate which is located on Pasternak substrate is presented in the current study. The plate’s core is made of saturated porous materials and face sheets are made of functionally graded piezo-electro-magnetic polymeric nano-composites. The displacement components of the plate described based on FSDT and MCST is employed to analyze the structure in micro scale. Length scale parameter of MCST shows the difference between macro and micro scales elasticity theory. Material properties of the three layers are varied across the thickness following different patterns and in addition, are temperature-dependent. The face sheets are subjected to electro-magnetic fields and pre loads. Using energy method and variational calculus, the equations are obtained and solved via GDQ as a numerical method for various boundary conditions. To examine the reliability of the results, they are compared with previous studies and verified. Effect of different properties and aspect ratio of the plate are investigated and highlighted. The results depicted by enhancing the porosity, the critical buckling load and maximum transverse deflection decreases and increases, respectively. Also increasing temperature leads the buckling load to more values and vice versa about deflection of the plate. The findings of this research can help to design and create more efficient structures especially smart one as sensors or actuators.

Magnetorheological fluids are materials that react to the applied magnetic field and are converted to the quasi-solid phase from the liquid one. Their applications in control and suppression of vibration have interested scientists nowadays. The present study is focused on the vibrational behavior of magnetorheological fluid circular plates that are embedded with magnetostrictive face layers. Magnetostrictive materials are also playing an important role in vibration control and are used widely in smart devices such as sensors and actuators. The structure is exposed to the transverse monotonic magnetic field and is located on the visco-Pasternak elastic substrate. Using Hamilton’s principle and based on classical plate theory, the motion equations and boundary conditions are extracted, and the generalized differential quadrature method is selected to solve them. Three different types of magnetorheological fluids are considered, and their effect on the results is discussed. The outcomes of this study can be used to design more capable and precise dampers, smart structures, and devices.

“…They appraised the effect of the magnetic field on the alteration of the natural frequencies under different boundary conditions. Also, oscillation response of viscoelastic sandwich plate with MR fluid core and functionally graded piezoelectric nanocomposite face sheets was accomplished by Ghorbanpour Arani et al (2018). They observed that the loss factor, unlike the natural frequency, decreases by enhancing magnetic field severity.…”

This study presents an investigation of the wave propagation of a rectangular sandwich composite plate with tunable magneto-rheological fluid core. The constituent parts of this rectangular sandwich composite plate are the base layer, magneto-rheological fluid core, and limiter layer. Magneto-rheological fluid core is embedded within the base and limiter layers. Also, the upper and lower layers are made of elastic materials. For obtaining the governing equations of motion, Hamilton’s principle and classical plate theory are used. After that, applying an analytical solution, the wave frequency and phase velocity of the propagated waves can be gained by solving eigenvalue problem. By investigating the effect of the magnetic field, the results emphasize that the magnetic field intensity is the most important factor for changing the value of the wave frequency and phase velocity. Besides, results show by enhancing the core-to-top layer thickness ratio, the wave frequencies reduce because magneto-rheological fluid core is softer in comparison to elastic layers. Therefore, magneto-rheological fluid layer operates similar to a damper. At the end, the influence of the thickness of magneto-rheological fluid core on the phase velocity is also discussed.
