Calculation-Experimental Technique for Determination of Physical and Mechanical Properties of Powder Materials

The paper deals with the stress and strain relationship in powder materials determined by the experimental studies of reference material samples having the known physical and mechanical properties and geometry. The quantitative analysis is carried out via extra- or interpolation of experimental data on the one hand, and selection and refinement of experimental results on the other. The theory of small elasto-plastic deformations can be used to investigate the stress-strain state of structural elements made of powder materials and subjected to quasi-static loading.
