Testing of steel 45 under complex loading along the cylindrical screw trajectories of deformation

The results of the experiment on complex loading of a thin-walled tubular steel specimen with three parameter action of axial force, torsion, and internal pressure are presented. The experiment was carried out on A.A. Ilyushin's testing complex SN-EVM. The program of the experiment in the deformation space is a cylindrical, helical trajectory with a displaced center of a screw curvature. Scalar and vector properties of the material steel 45 were investigated.
