Abstract
Three directions of development of kinetic indentation methods. Physical-energetic analysis of the indentation force diagram according to ISO 14577. Physical theory and universal criterion for the macrohardness of a material. Model of the physical process, thermomechanical potential, function of the state of the kinetic macroindentation process. Method for determining the physical function and unit of measurement of the kinetic macrohardness of a material. The ratio of the values of the empirical (standard) and physical macrohardness of the material. Physical reason for the appearance of the size effect in empirical indentation methods. The principle of determining the standard value of physical macrohardness.
