Abstract
Torsional deformations of cylindrical bodies with magnetizable elastomers in a uniform magnetic field are considered. During theoretical research, different models of viscoelastic materials are used. Experimental studies of stress relaxation in a magnetic field are carried out, and the models that consider stress relaxation are used to describe the experiment. Dependences of the shear moduli and viscosity coefficients of magnetizable elastomers on the magnetic field strength are found experimentally. Tables 1, Figs 10, Refs 9.
