Уравнение индентирования

Abstract

On the basis of the known relations used in the automatic indentation method, the equation, which reflects the basic regularities of this process and establishes the direct connection between parameters of the indentation diagram, hardness, and the normal elasticity modulus, is analytically deduced. The physical essence of this equation is determined. Experimental confirmation is obtained at the indentation of materials of different kinds more than 30 names. Indentation constants which reflect the presence of a basic opportunity of the existence of limit values for the indentation depth of an indentor and the hardness of materials are established. Opportunities to use the obtained relations are shown.
