متن کاملEnergy 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 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...
متن کاملLarge-strain behaviour of Magneto-Rheological Elastomers tested under uniaxial compression and tension, and pure shear deformations
The large-strain behaviour of Magneto-Rheological Elastomers (MREs) is characterised experimentally under uniaxial compression, uniaxial tension and pure shear deformation both in the absence and in the presence of magnetic fields. MREs are ‘’smart’ materials that can alter their properties instantaneously by the application of external stimuli. They hold great potential for use in adaptive sti...
