Paper Abstract
A plastic deformation of the metal significantly changes its internal structure and greatly influences many mechanical,
physical and chemical properties. In the plastic deformation process increases the electrical resistance, changes the
magnetic properties and decreases the thermal conductivity and the workability of the metal. But this influence is
especially evident in the measurement of the hardness of the deformable body, which is connected directly to an increase
in the yield strength of the material, i.e. the hardening. Hardness measurements were made on samples of whole over the
entire length. After the experimental study by rupturing samples were carried out repeated measurements of hardness
over the entire length. Modeling the process of rupturing samples was carried out by finite element method (FEM) in
Academical version of ANSYS. The phenomenological link between the calculated and experimental values of hardness
and stress state of the sample were determined. The obtained results are important for evaluation of the results of
international comparisons of the national standards of hardness. As the perspective directions for the practical application
of the results proposed evaluation and prediction of hardness standard measures the hardness of the first rank in their
manufacture. The predictions of the FEM models were compared with experimental data, and the accuracy of these
predictions was quite satisfactory.
