Indentation is the most accurate, theoretically and experimentally confirmed standardized method for determination of physical and mechanical properties on micro- and nanometer level for materials with a fine structure, local gradient of properties in the state of intensive plastic deformation or after thermal impact, as well as superhard, brittle and elastic materials, mechanical properties of which cannot be determined by other processes. Methodology of determination by precision means is developed within a promising research field, which can be called nanotesting mechanics. 8 References, 9 Figures.
