Model of magnetorheological elastomers
Journal of Applied Physics, 1999Magnetorheological elastomers consist of natural or synthetic rubber filled with micron-sized magnetizable particles. During curing of the elastomer, an applied magnetic field aligns the particles into chains. The shear modulus of the resulting cured material is sensitive to magnetic fields of several kOe magnitude.

Damping Properties of Magnetorheological Elastomers
Advanced Materials Research, 2017Magnetorheological elastomers (MREs) are a kind of smart materials, which change the mechanical properties (viscoelastic characteristics) under the magnetic field action. In the paper the determination of damping properties (reactive force) of specimens made out of magnetorheological elastomers is presented.

Sensing Behavior of Magnetorheological Elastomers
Journal of Mechanical Design, 2009A magnetorheological elastomer (MRE) is comprised of ferromagnetic particles aligned in a polymer medium by exposure to a magnetic field. The structures of the magnetic particles within elastomers are very sensitive to the external stimulus of either mechanical force or magnetic field, which result in multiresponse behaviors in a MRE.

Magnetorheological Elastomers: Experimental and Modeling Aspects
2016Magnetorheological elastomers (MREs) are active composite materials that deform under a magnetic field because they are made of a soft elastomer matrix filled with magnetizable micrometric particles. Along with short response times and low magnetic inputs, not only do MREs alter their viscoelastic properties and stiffness in response to external ...

Development and characterization of magnetorheological elastomers
Journal of Applied Polymer Science, 2007AbstractA new class of materials termed magnetorheological elastomers (MREs) are developed that respond to externally imposed magnetic fields. Magnetic particles are embedded in viscoelastic solids or liquid elastomeric precursors. This kind of composite demonstrates a unique combination of good magnetic controllability and elastic properties ...

Potential Applications of Magnetorheological Elastomers
Applied Mechanics and Materials, 2014Magnetorheological elastomer still becomes interested topics among researchers since the rheological properties can be controlled by applying external magnetic field by means of adjustable modulus of elasticity. In this paper, the current application of MRE and related patents will be discussed. Potential application of MRE focused on three main areas.

STUDY OF UTILIZABLE MAGNETORHEOLOGICAL ELASTOMERS
Electrorheological Fluids and Magnetorheological Suspensions, 2007This paper presents two kinds of magnetorheological elastomers (MREs). One is composed of appropriate silicon rubber, carbonyl iron particles and some other materials. It is cured under a strong magnetic field at a room temperature. Its shear modulus change from 0.34MPa at zero magnetic field to 3.34MPa at 1T magnetic field, the relative MR effect ...

Magnetostrictive effect of magnetorheological elastomer
Journal of Magnetism and Magnetic Materials, 2008Abstract Magnetorheological elastomer (MRE) has been known for its magnetic field-dependent stiffness, but only a few works study its magnetostrictive property. The aim of this paper is to present results of studies on magnetostriction of the MRE consisting of carbonyl iron particles displaced in the matrix made of a silicone rubber.

Shear properties of a magnetorheological elastomer
Smart Materials and Structures, 2003This paper presents an experiment testing the damped free vibration of a system composed of a magnetorheological elastomer and a mass. The goal of this experiment was to obtain the dependence of the natural frequency and the damping ratio of the structure on the applied magnetic field.
