Research of viscoelastic properties of magnetizable elastomers

Abstract The torsional deformations of cylindrical bodies with magnetizable elastomers in a uniform magnetic field are investigated. The model of a viscoelastic material, which takes into account residual deformations (a generalization of the Kelvin–Voigt model), is used for a theoretical research. The sample elongation is described by the Mooney–Rivlin model. The dependence of shear and viscosity coefficients and of residual deformations on the magnetic field intensity is determined from a comparison of theoretical and experimental results.
