To verify the mathematical model of the theory of processes, numerical
calculations of the complex elastoplastic deformation of St3 steel along a flat curvilinear
strain trajectory under combined tension-compression with torsion were carried out. The
numerical calculations are compared with the experimental data obtained by the authors on
the experimental complex SN-EVM on thin-walled tubular specimen. It is shown that the
used mathematical model qualitatively and quantitatively satisfactorily describes the main
effects of complex plastic deformation for the class of strain trajectories under consideration.
