Energy conversion in magneto-rheological elastomers
Magneto-rheological (MR) elastomers contain micro-/nano-sized ferromagnetic particles dispersed in a soft elastomer matrix, and their rheological properties (storage and loss moduli) exhibit a significant dependence on the application of a magnetic field (namely MR effect). Conversely, it is reported in this work that this multiphysics coupling is associated with an inverse effect (i.e. the dep...

متن کاملMagnetic induction measurements and identification of the permeability of Magneto-Rheological Elastomers using finite element simulations
The isotropic and anisotropic magnetic permeability of Magneto-Rheological Elastomers (MREs) is identified using a simple inverse modelling approach. This involves measuring the magnetic flux density and attractive force occurring between magnets, when MRE specimens are placed in between the magnets. Tests were conducted using isotropic MREs with 10–40% and for anisotropic MREs with 10–30%, par...
متن کاملOn the stiffening effect of magneto-rheological elastomers
Magneto-rheological elastomers (MREs), a class of polymer-based composites with dispersed magnetic filler particles, are known for their tunable stiffness. The magnetic-field-induced stiffening effect, namely the magneto-rheological (MR) effect, is often attributed to the magnetic dipolar interaction. The direct attraction between two magnetic dipoles could increase the shear modulus of the mat...
متن کاملEqui-biaxial tension tests on magneto-rheological elastomers
A bespoke test rig has been designed to facilitate testing of magneto-rheological (MR) elastomers (MREs) under equi-biaxial tension using a standard universal test machine. Tests were performed up to 10% strain on both isotropic and anisotropic MREs with and without the application of an external magnetic field. Assumptions regarding the material’s response were used to analyse stress–strain re...
