The article presents the results of numerical modeling of deformation of steel 45 using general and linearized models of the theory of processes on flat smooth trajectories with curvilinear sections. The calculation results are compared with experimental data on the deformation of thin-walled cylindrical specimens on using the SN-EVM testing system. It is shown that for the implemented types of experimental trajectories, symmetric about the bisectors of angle, the postulate of isotropy by A.A. Ilyushin performed quite well.
