AnnotationA method which can be used to carry out the characterization of linear hereditarily-elastic material torsion elements subjected to the Boltzmann-Volterra superposition principle is proposed. The method is based: on the solution of mathematical model equations of the behavior of torsion under constant force loading applied to the end part using finite element software "ANSYS"; using of the experimental data of elastic compliance function parameters of torsion bar end; determining of "instantaneous" shear modulus of rubber layers providing experimental "instantaneous" displacement in the plane of the stroke.
