Energy Concept of Hardness by the Kinetic Sphere Indentation

Abstract:

Energy hardness is defined as energy density of material’s plastic displacement from the initial surface level. It is convenient to determine it from the kinetic indentation diagram constructed in coordinates P - h, where P is the relative load, h is the relative penetration of a spherical indenter. With that the relative energy density is equal P/h multiplied by the parameter C_p(h) , where varies within a range narrow for the constructional materials. The relative error of the energy hardness determination by this approach does not exceed 5%.
