Experimental construction of plasticity functionals for the deformation trajectories of the two-link broken lines in the experiments with continuous cylindric samples. (Russian) Zbl 0898.73025

The paper deals with three experimental methods of plasticity functional constructions in the theory of elastoplastic processes. In the experiments with continuous cylindric samples with circular cross-section it is assumed that the deformation trajectories are two-link broken lines. The samples are loaded by an axial force and by a rotating moment simultaneously changing according to a prescribed program.
