Conceptions of parabolic staging of strain-hardening curves presented in different ways are systematized. A new method for determining the parabolic stages of strain hardening based on the quadratic-parabolas’ mesh is offered.

Key words: true stress, deformation, analytical description of the deformation curves, tensile, compression, strain gage.
