In this research, semi-active control of sandwich plates with electro-rheological (ER) core and carbon nanotubes-reinforced composite facesheets using smart ER dampers is studied. Sandwich plate is subjected to the external electric field and rested on orthotropic visco-Pasternak foundation. The material properties of ER core and nanocomposite facesheets are obtained by Yalcintas model and Eshelby-Mori-Tanaka approach, respectively. The governing equations of motion are solved by a combination between finite element and Newmark methods for clamped and simply supported boundary condition. The effects of various parameters such as applied voltage, controlled electric field and initial gap of the electrodes on the vibration suppression time are discussed. The results show that the settling time of system introduced in this work is much less than previous researches in this field which is a very important advantage.

“…As illustrated in Figure 1(b), a four-node rectangular element is considered for the finite element analysis of the sandwich composite plate with MRE core subjected to in-plane load N ( t ). This four nodes rectangular element with seven degrees of freedom per node is similar to the element that has been used by Yeh and Chen [6,25] for dynamic analyses of an ERF/MRE core sandwich plate with a single layer orthotropic or isotropic faces. However, the present element has laminated composite faces.…”

“…Oyadiji [5] conducted an experimental study to show the effect of ER damping layer on vibration characteristics of a composite sandwich plate. The pre-yield region behavior of the ER fluid has been used by Yeh and Chen [6,7] for vibration and dynamic stability analysis of a rectangular plate with an ER fluid core. Buckling, vibration and dynamic stability of a sandwich beam with MR fluid core layer has been investigated by Yeh and Shih [8].…”

The dynamic stability of composite sandwich plates with a smart elastomer layer subjected to an axial periodic load is investigated. A finite element model of the composite sandwich plate with Magnetorheological elastomer (MRE) core is developed. A MRE layer, which its mechanical properties change with the applied magnetic field, is used as a damping layer to improve the stability of the structure. Due to the intrinsic characteristics of the MREs, these materials commonly operate in their pre-yield region. In this region, complex shear modulus is used for these materials. The effect of different parameters such as stacking sequences, boundary conditions, geometry of the sandwich plate, thickness and partial activation of the MRE layer on the damping treatment and stability boundaries is investigated. The presented results show that the application of an MRE layer as a core in the composite sandwich plate changes the stability region of the structure. Therefore, the instability boundaries can be manipulated to achieve the desired dynamic response of the structure.

“…The dynamic stability problems of such a sandwich plate subjected to an axial dynamic force are investigated using FE method to calculate instability regions in sandwich plate, 137 which is orthotropic facing. 138 A new novel trigonometric zigzag theory is developed in combination with an efficient C 0 continuous isoparametric serendipity FE model for the analysis of laminated composite and sandwich plates. The theory is based on shear strain shape function assuming nonlinear distribution of transverse shear stresses.…”

Many review articles were published on free vibration and buckling of laminated composites, sandwich plates, and shells. The present article reviews the literature on the buckling and free vibration analysis of shear deformable isotropic and laminated composite sandwich plates and shells using various methods available for plates in the past few decades. Various theories, finite element modeling, and experimentations have been reported for the analysis of sandwich plates and shells. Few papers on functionally graded material plates, plates with smart skin (electrorheological, magnetorheological, and piezoelectric), and also viscoelastic materials were also reviewed. The scope for future research on sandwich plates and shells was also accessed.
