摘要

Results related to the study of thermoviscoplastic deformation processes of a body element along trajectories of arbitrary curvature and small torsion are provided. The results are obtained by using the derived constitutive equations that appear in functional form and are formulated on the basis of uniaxial-tension and combined-loading tests of thin-walled tubular specimens along bilinear loading trajectories with an angle of 90° between the branches. The assumptions used for construction of the constitutive equations were experimentally verified. It is shown that, through inclusion of the delay of rectorial and scalar properties of a material, the deformation process of a body element under combined loading along the three-dimensional trajectories can be adequately described.
