“…The displacement profile of the core layer was also obtained using compatibility conditions of three layers. Application of FE method has been extensively reported to derive governing equations of motion of MR/ER sandwich plates under different geometry boundary conditions (Cho et al, 2005;Lu and Meng, 2006;Yeh, 2007bYeh, , 2010bYeh, , 2011aYeh et al, 2009). Eshaghi et al (2015aEshaghi et al ( , 2015c) employed a sandwich plate element, as depicted in Figure 13, to derive governing equations of motion of an MR sandwich plate.…”

“…Sandwich structures with annular plate, skew plate, and shell face layers Although rectangular sheets have been widely employed to serve as the constraining and base layers for MR/ER sandwich plates, application of annular (Yeh, 2007a(Yeh, , 2007b(Yeh, , 2010a(Yeh, , 2010b(Yeh, , 2011a(Yeh, , 2012Yeh et al, 2009) and skew plates (Narayana and Ganesan, 2007) has also been reported. The effects of different parameters such as magnetic/electric field, core layer thickness, aspect ratio, and boundary condition on the annular or skew plates are similar to those of the Figure 14.…”

During past four decades, applications of magnetorheological and electrorheological fluids in adaptive sandwich structures have been widely studied, primarily for the purpose of vibration control. The rapid response time of controllable magnetorheological/electrorheological fluids to an applied magnetic/electric field and reversible variations in their stiffness and damping properties have been the key motivations for adaptive structures applications. This article presents a comprehensive review of the reported studies on applications of magnetorheological/electrorheological fluids for realizing active and semi-active vibration suppression in sandwich structures. The review focuses on methods of characterizing the magnetorheological/electrorheological fluids in the pre-yield region, magnetic/electric field-dependent phenomenological models describing the storage and loss moduli of fluids, experimental and analytical methods developed for vibration analysis of sandwich structures with magnetorheological/electrorheological fluid treatments, analysis of structures with partial magnetorheological/electrorheological fluid treatments and optimal treatment locations, and developments in control strategies for vibration suppression of magnetorheological/electrorheological sandwich structures. The studies on dynamic responses of fully and partially treated magnetorheological/electrorheological-based sandwich beams, plates, shells, and panels are also discussed, including the mathematical modeling methods and associated assumptions, methods of solutions, and experimental methods.

“…A sandwich plate was fully treated with an ER fluid core layer and a constraining layer to improve the vibration behavior of the system by Yeh et al. [3,4]. They employed the Rayleigh–Ritz method to derive the equations of motion for the annular sandwich plate and they investigated the effects of natural and loss factors on the dynamic behavior of the sandwich annular plate.…”

In this paper, the free vibration and buckling analyses of the cylindrical sandwich panel with magneto-rheological fluid layer for simply supported boundary conditions was performed based on an improved higher order sandwich panel theory. This paper deals with investigation of the effects of magnetic field, geometrical parameters such as the core thickness to the panel thickness ratio, MR layer thickness to the panel thickness ratio and the fiber angle on the natural frequencies, loss factors and buckling loads corresponding to the first four mode shapes. In order to validate the results obtained from the present study, the cylindrical sandwich panel was simulated and analyzed in finite element software ABAQUS. A good agreement was observed between the results of present method and those extracted from simulation.

“…The Rayleigh-Ritz method was number of elements in the z-direction used to calculate the damping characteristics of the sandwich annular system with ER core layer by Yeh [23]. Afterwards, Yeh et al [22,24] adopted the discrete layer finite element method to analyze the vibration characteristics of isotropic and polar orthotropic annular sandwich plate with ER core layer. The vibration and damping characteristics of the orthotropic cylindrical shells with ER core layer are studied by the discrete layer finite element method.…”
