Stress induced by the striction of hybrid magnetoactive elastic composites

In this study we experimentally examine the mechanical stress induced by the striction of hybrid magnetoactive elastic composites in the direction parallel to an externally applied magnetic field. Elastic samples based on a polydimethylsiloxane matrix with embedded spherical magnetic soft carbonyl iron particles, spherical magnetic hard NdFeB-alloy particles as well as on a mixture of the two kinds of powder are under investigations. An effect of the structuring and pre-magnetization of the samples on the stress induced by the magnetodeformational effect is evaluated. (C) 2017 Elsevier B.V. All rights reserved.
