چکیده
Smart composite materials have been an active field of research in the last few decades. Magnetorheological elastomers (MREs) are examples such smart composites and they show a coupling between magnetism elasticity. MREs heterogeneous consist magnetic particles silicone-based elastomer. To describe predict behaviour macroscopic continuum accurately, microstructural information needs to be taken into account analysis materials. Therefore, combined approach called multi-scale is used consider various scales observation simultaneously. The concept Representative Volume Element (RVE) typically employed by approaches micro scale, thus size RVE becomes model parameter techniques. This has motivated determination derivation magnetoelastic constitutive relations terms sizes our paper. finite element method statistical based on coefficient variation determine MREs. results that it possible lower bound for MRE. Furthermore, parametric study conducted examine sensitivity different material properties constituents. It was found primarily set contrast properties, i.e. stiffness, permeability coefficients.

Modeling of a magnetorheological elastomer-based isolator
A variable stiffness and damping isolator (VSDI) is designed and developed employing MREs. A double lap shear test has been carried out to characterize two MRE based VSDIs under quasi-static shear loading. A phenomenological model which can capture the behavior of the VSDI is developed and related parameters are identified using experimental data. Both experimental and theoretical modeling resu...
متن کاملElectrical resistivity mechanism in magnetorheological elastomer
Magnetorheological elastomers (MRE) are smart materials made by aligning magnetic microparticles inside a liquid polymer. Once the polymer is cured, this anisotropic structure is kept, giving to the composite new properties such as a large change of electrical resistivity with applied pressure. In order to understand the conduction mechanism in such composite, the influence of pressure on the e...

متن کاملDetermination of the Size of Representative Volume Elements for Discontinuous Fibre Composites
Discontinuous fibre composites can be rapidly manufactured using automated processes, with low production costs compared with textile reinforcements [1]. The level of flexibility offered by discontinuous fibre composites can however make efficient design challenging, as additional material and process parameters complicate material selection and quality can be difficult to control compared with...
