Experimental identification of the magneto-mechanical behavior and mathematical modeling of the interaction force between the micro size ferromagnetic particles

Abstract

This paper is devoted to an experimental and theoretical study of the magneto-mechanical behavior of an elastomer loaded with 25% of ferromagnetic particles of micrometric size; elaborated under the action of a magnetic field. The characterization of the rheological properties and the interaction between the micron size ferromagnetic particles as a function of the intensity of the magnetic field are studied. The results obtained clearly show a high energy dissipation properties of the composite, accentuated by its modified structure from the interaction forces between the particles that are aligned, which gives adjustable viscoelastic structures properties, depending on the volume fraction of particles and the magnetic field intensity.
