An analytical investigation into the use of magneto-rheological elastomers to suppress flexural waves in beams
(2017-01-01)
Magneto-rheological elastomers (MRE) are materials that change their stiffness and damping properties when subject to a magnetic field. They have evolved from magneto-rheological fluids which have some disadvantages, in ...
Magnetic nanocomposites (SR/IRON) type isotropic MRE directed to vibration absorption systems
(Ieee, 2017-01-01)
In recent decades, an increasing effort has been made not only to foster cost-effective, competitive and innovative industries but also to create smart materials. In this work, we present the morphological, magnetic and ...

Numerical Simulations of Stick Percolation: Application to the Study of Structured Magnetorheological Elastomers
(American Chemical Society, 2014-08)
In this article we explore how structural parameters of composites filled with one-dimensional, electrically conducting elements (such as sticks, needles, chains, or rods) affect the percolation properties of the system. ...
Magnetic and elastic anisotropy in magnetorheological elastomers using nickel-based nanoparticles and nanochains
(Amer Inst Physics, 2013-12-06)
Nickel (Ni) based nanoparticles and nanochains were incorporated as fillers in polydimethylsiloxane (PDMS) elastomers and then these mixtures were thermally cured in the presence of a uniform magnetic field. In this way, ...
