Experimental verification of postulate of isotropy and mathematical modeling of elastoplastic deformation processes following the complex angled nonanalytic trajectories

The results of numerical simulation for 45 steel deformation with the use of general and linearized models of the theory of processes along flat smooth trajectories with curvilinear sectors are presented. The results of calculation are compared with the data of thin-walled cylindrical specimen deformation experiment, carried out on SN-EVM testing complex. It is shown that for the realized types of experimental trajectories symmetric with respect to the bisector of a right angle Ilyushin.s postulate of isotropy is fulfilled in the proper way.
