Abstract
The physical properties of force diagrams of kinetic macroindentation of materials by the Brinell sphere are studied. Theoretical and experimental substantiation of physical concepts of the function and number of hardness, new analytical methods for analyzing data from the process of kinetic macroindentation. Universal physical unit of material macrohardness. Method for determining the function and number of physical macrohardness of the kinetic indentation of the material. The reason for the size effect in standard empirical methods for determining hardness is shown. A correct physical method for comparing and translating the hardness values of different scales is proposed. To analyze the force diagrams obtained by different indenters, to determine the correct values of the physical and empirical hardness of macroindentation, physical algorithms and formulas have been developed. The prospect of using the research results for different ranges of kinetic indentation, improving the ISO 14577 standard is discussed. An example of using the physical parameters of hardness in universal methods for calculating the parameters of strength, fatigue and durability of materials.

Keywords
physical macrohardness of material kinetic indentation, theory, method, function, number, universal unit, application.
