Study of the Lag Trace of Scalar and Vector Properties of Steel 45 under Deformation along Offset-Fan Trajectories

The paper is devoted to investigation of complex elastoplastic deformation processes in thin‑walled cylindrical shells and the resulting “dives” of the stress‑vector modulus on experimental deformation diagrams. Two‑segment piecewise‑linear paths were chosen as deformation trajectories. After preliminary proportional tension with torsion to the level E1 = E3 = 1
