“…In the second case, flutter frequencies and critical non-dimensional aerodynamic pressure of the sandwich panel with fully treated MR fluid core under supersonic flow are compared with those reported by Asgari and Kouchakzadeh (2016) for clamped–clamped and simply-supported boundary conditions. Geometrical and physical properties of the panel are assumed the same as mentioned in Asgari and Kouchakzadeh (2016). The results of comparison study corresponding to zero magnetic field are listed in Table 2.…”

“…Supersonic panel flutter semi-active control of ER-based cylindrical shell and rectangular sandwich plates was investigated by Hasheminejad et al (2013); Hasheminejad and Motaaleghi (2014, 2015) used Runge–Kutta time integration algorithm and sliding mode control method. Recently, Asgari and Kouchakzadeh (2016) investigated the aeroelastic characteristics of MRF sandwich beams in supersonic airflow. They used the assumed mode method to solve the equation of motion.…”

This study considers the aeroelastic instability of a partially treated magneto-rheological fluid sandwich panel in supersonic airflow. The linear first-order piston theory is used for modeling the aerodynamic pressure. Using classical Hamilton’s principle along with the finite element method, the equations of motion are derived. The critical value of the non-dimensional aerodynamic pressure is obtained by traditional p-method scheme. The validity of the finite element formulation is examined through comparison with those obtained from the assumed mode formulation and the available results in the literature. Various parametric studies including the effects of applied magnetic field, core and constraining layer thicknesses are examined for several configurations of the core at simply-supported and clamped–clamped boundary conditions. The results show that the critical non-dimensional aerodynamic pressure of the sandwich panel is influenced not only by the magnetic field strength, core and constraining layer thicknesses but also strongly by the configuration of the core.

“…Also, the natural frequency and damping ratio of the MRF core sandwich beams increased with an increase in the applied magnetic flux density. [8][9][10][11][12][13][14][15][16][17][18][19][20] From the literature, it is observed that many researches have been done on aluminum sandwich beam with MRF core. The studies on the CGRP-PMC-MRF core sandwich beam are yet to be explored.…”

The semi-active vibration control of sandwich beams made of chopped strand mat glass fiber reinforced polyester resin polymer matrix composite (PMC) and magnetorheological fluid (MRF) core were experimentally investigated in this study. Two-, four- and six-layered glass fiber reinforced polyester resin polymer matrix composites were prepared using the hand-layup technique. The magnetorheological fluid was prepared in-house with 30% volume of carbonyl iron powder and 70% volume of silicone oil. Nine cantilever sandwich beams of varying thicknesses of the top and bottom layers glass fiber reinforced polyester resin polymer matrix composite beams and middle magnetorheological fluid core were prepared. The magnetorheological fluid core was activated with a non-homogeneous magnetic field using permanent magnets. The first three modes, natural frequencies and damping ratios of the glass fiber reinforced polyester resin polymer matrix composite-magnetorheological fluid core sandwich beams were determined through free vibration analysis using DEWESoft modal analysis software. The amplitude frequency response of the glass fiber reinforced polyester resin polymer matrix composite-magnetorheological fluid core sandwich beams through forced vibration analysis was determined using LabVIEW. The effect of various parameters such as magnetic flux density, thickness of glass fiber reinforced polyester resin polymer matrix composite layers and magnetorheological fluid core layer on the natural frequencies, damping ratio and vibration amplitude suppressions of the glass fiber reinforced polyester resin polymer matrix composite-magnetorheological fluid core sandwich beams was investigated. Based on the results obtained, 2 mm thickness top and bottom layers glass fiber reinforced polyester resin polymer matrix composite and 5 mm thickness magnetorheological fluid core sample have achieved a high shift in increased natural frequency, damping ratio and vibration amplitude suppression under the influence of magnetic flux density.
