Fig. 24.3 To building the plastic material elongation diagram
dynamic properties of the “sample—loading device” system rather than the strain
properties of the specimen material, which creates an illusion of ideal plasticity.
Having this in mind, it is logical to represent the yield process on the plateau as
having constant stress equal to the upper yield stress and to depict the hardening
process with a single curve in both visible and hidden zones of the diagram.
