On assumption, that nonlinearity due to the plastic deformation may be described by tensor and nonlinear equations, the scalar functions characterizing the form variation are analyzed. It is shown that these functions may be determined by experimental diagrams in case of the simple stress states, the study results are presented as plots from which it follows that the variation of all characteristics is more distinctly revealed at stresses beyond the yield point.
