摘要

考虑了具有可磁化弹性体的圆柱体在均匀磁场中的扭转变形。在理论研究中，使用了不同的粘弹性材料模型。对磁场中的应力松弛进行了实验研究，并使用考虑应力松弛的模型来描述实验。实验发现了可磁化弹性体的剪切模量和粘度系数与磁场强度的关系。表1，图10，参考文献9。

Experimental research of viscoelastic properties and stress relaxation of magnetizable elastomers

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.
