Elastic properties of a magnetic elastomer

Magnetoactive (aka magnetorheological) elastomer is a composite material consisting of an elastic matrix and magnetic filling substance. A study dedicated to the relationship between its viscoelastic parameters and the strength of the external magnetic field has been done. Under the influence of a field, the material can demonstrate elasticity and viscosity increased by ten folds. The elastic properties of the composite remaining under those conditions heavily depend on the degree of deformation of the sample. Thus, this type of magnetic composite is a prospective material for being used as the working body in controllable dampers.
