Magnetic-Driven Viscous Mechanisms in Ultra-Soft Magnetorheological Elastomers Offer History-Dependent Actuation with Reprogrammability Options. [PDF]
Adv Sci (Weinh)Magnetically induced microstructural rearrangements in ultra‐soft magnetorheological elastomers modulate their viscoelasticity, enabling programmable mechanical memory. Magnetic actuation induces long‐term viscous relaxation and double‐bumping stress responses due to particle chain formation.

Equi-biaxial tension tests on magneto-rheological elastomers [PDF]
Smart Materials and Structures, 2015 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.

Field-stiffening effect of magneto-rheological elastomers
International Journal of Solids and Structures, 2013 AbstractMagneto-rheological elastomers (MREs) are a class of soft active materials known for their tunable stiffness. Dispersed with magnetic particles, these polymer-based composites tend to be stiffer under a magnetic field. Such a stiffening effect is often attributed to the magnetic interaction among filler particles, but the well-acknowledged ...

Fatigue life prediction of magneto-rheological elastomers in magnetic field [PDF]
Materials Research Express, 2021 Abstract Fatigue life is one of the most important characteristics of materials. Predicting fatigue life in magnetorheological elastomer (MRE) under combined and repetitive loads is an unavoidable step to increase the safety coefficient of MREs.
