Effect of lubrication on the mechanical behavior of magnetorheological elastomers in compression mode

The effect of the lubrication on mechanical behavior magnetorheological elastomers (MREs) in compression mode is experimentally studied. According to ISO 7743, there are two procedures characterize specimens mode. Differences properties these materials between lubricated and non-lubricated conditions must be considered if devices such as vibration absorbers isolators developed. With lubrication, said uniaxial homogeneous, thus material can obtained. Without tests easier perform but results strongly dependent piece shape. In this study isotropic anisotropic MREs with iron particle volume concentrations 10, 20, 30 40% tested under different strain amplitudes, prestrain magnetic fields for a frequency range up 300 Hz, without lubrication. Important design parameters like amplitude, field dependency showed
