Magnetodeformational effect of the magnetoactive elastomer and its possible applications

Abstract

Magnetodeformational effect (deformation in non-uniform magnetic field) of magnetoactive elastomer has been studied experimentally. It has been shown that in non-uniform magnetic field this material is able to be reversibly deformed by 250%. In dynamic regimes the deformations under elongation are up to 80% while the ones under compression are 2%. Effective frequency range of the material is up to 100 Hz. As a possible application of the material a magneto controlled valve of flow rate (gas, liquid) was developed. © Published under licence by IOP Publishing Ltd.
