“…For nanocomposite face sheets, the stress–strain relations can be written as where σ and Q denote the stress and stiffness constants, respectively. In this paper, the stiffness constants of CNTs reinforced composite face sheets are calculated by Eshelby–Mori–Tanaka approach [18]. When the layers are completely coupled with the core, the compatibility conditions in r-θ and r–x plan according to layers displacement field at the upper interfaces are …”

“…As one of these works, Ghorbanpour Arani et al. [18] investigated the smart sandwich plate which is subjected to an electric field and is rested on the Winkler–Pasternak foundation. The material properties of ER core are determined by Don and Yalcintas models and for nanocomposite, face sheets are used from Eshelby–Mori–Tanaka approach.…”

In this research, the vibration analysis of a cylindrically curved sandwich plate rested on Winkler–Pasternak foundation is investigated. The curved sandwich plate consists of a rheological core and nanocomposite top and bottom layers which are included in polyvinylidene fluoride matrix and carbon nanotubes fiber. The core has electric properties, and it is affected by applying electric fields. At first, the governing relations for different layers are written, separately, in order to determine the constitutive equations of the cylindrically curved sandwich plate. Then, differential motion equations are derived by applying the energy method and Hamilton’s principle. With regard to achieving the set of coupled equations, an appropriate analytical approach is proposed to solve them which can be considered as SSCC and SSSS boundary conditions. Also, it is observed that increasing the volume fraction of carbon nanotubes in face sheets leads to increase in the stability of the electro-rheological sandwich plate. This ﬁnding can be employed to design building smart structures, military, aviation, marine and automotive.

“…Analytical solution for free vibration of three-layer sandwich plate with ER core was presented by Soleymani et al (2015). Vibration analysis of electro rheological sandwich plate with CNT reinforced facing sheets rested on Winkler Pasternak foundation was carried out by Arani et al (2017). Based on classical thin plate theory for face sheets and first order shear theory for the core layer, free and forced vibration of a sandwich plate with electro-rheological fluid core and functionally graded facing layers was investigated by Gholamzadeh Babaki and Shakouri (2019).…”

In this study, free vibration and damping behavior of cylindrical sandwich panel with electro-rheological core and graphene platelets reinforced composite (GPLRC) facing sheets based on first-order shear deformation theory of thick cylindrical shells referred by Qatu (FSDTQ) is investigated. Effective material properties of graphene platelets reinforced composite are determined according to the Halpin–Tsai micromechanical model. The governing equations of motion with required boundary conditions are derived using Hamilton’s principle. Afterward, these equations are solved analytically using the Fourier series solution for simply-supported boundary conditions, and for the other edges boundary conditions, we used the generalized differential quadrature method. The exactness and correctness of the present formulation are validated by comparing the results with those of existing literature. Finally, the influences of various parameters such as the electric fields, geometrically parameters, boundary conditions, the volume fraction of GPL, and GPL distributions pattern on vibration behavior and modal loss factor is examined. According to the results, the influence of the GPL volume fraction and electric field on the frequencies and modal loss factor is significant. This achievement can help design intelligent controlling structures for various applications.

“…They observed that increasing the volume fraction of carbon nanotubes (CNTs) in the panel leads to an increase in the stability of the ER sandwich panel. 14 In 2018, they studied the vibration analysis of viscoelastic sandwich panels bonded to the Pasternak foundation. The results of the module show that increasing the thickness ratio of the core to the panel results in a decrease in the natural frequency because the MRF core is softer than the nanocomposite panel.…”

A magnetorheological fluid damper is a device in which a magnetorheological fluid is filled in a damper. In this device, the magnetic field is controlled by an external current (voltage) so that the magnetic force of a piston inside the damper changes like an electromagnet. The damping force of the damper is controlled by changing the magnetic force of the piston. With the increasing magnetic force of the piston, the viscosity of the magnetorheological fluid in the damper increases. The primary aim of this study was to maximize the magnetic flux density and identify the following influencing factors from the relevant literature: piston and outer tube materials, piston length, piston diameter, cylinder wall thickness, damper channel clearance, gap channel length, current, and magnetorheological fluid. A magnetic circuit analysis was performed using ANSYS Maxwell, and the optimal parameter combination was identified using the Taguchi method. The analysis of variance was used to examine the influence of various factors on quality characteristics. This study helps understand the relation between structure size, material, and magnetic flux density and contributes to future generations of magnetorheological fluid damper design analysis.
