A magneto-rheological elastomer vibration isolator for lightweight structures
Meccanica, 2019Magneto-rheological elastomers (MRE), consisting of elastomeric matrix containing ferromagnetic particles, are a kind of smart material, whose mechanical properties are controllable via applied magnetic fields. In this paper, the possibility of adopting these materials to realize vibration isolators for lightweight structures is evaluated.

Modeling of Magneto-Rheological Elastomers for Harmonic Shear Deformation
IEEE Transactions on Magnetics, 2012Magneto-rheological elastomers (MREs) are a class of smart materials which can adjust their modulus or stiffness by an applied magnetic field. Thus, MREs can be used as controllable stiffness elements in various engineering systems. In order to use them for engineering applications, characterizations of MRE behaviors under magnetic fields and ...

Characteristics of Magneto-Rheological Elastomer under Stick-Slip Condition
Key Engineering Materials, 2020This paper examines the characteristics of stick-slip phenomena between the glass plate and Magneto-Rheological Elastomer (MRE) surface. Stick-slip phenomena are the spontaneous jerking motion that occurs while two objects are sliding over each other, usually accompanied by noise.
