A novel procedure of “graphical superposition” was proposed to determine the representative yield stress <jats:italic>Y</jats:italic><jats:sub>R</jats:sub>. It was confirmed that the concept of <jats:italic>Y</jats:italic><jats:sub>R</jats:sub> applied to elastic-perfectlyplastic solids is sufficient enough for describing the indentation behavior of strainhardening elastoplastic solids. The representative plastic strain of ε<jats:sub>R</jats:sub> (plastic) ≈ 0.22 tan β, at which <jats:italic>Y</jats:italic><jats:sub>R</jats:sub> is prescribed, is applicable to the strain-hardening elastoplastic solids, affording a quantitative relationship of <jats:italic>Y</jats:italic><jats:sub>R</jats:sub> = <jats:italic>Y</jats:italic> + ε;<jats:sub>R</jats:sub> (plastic) × <jats:italic>E</jats:italic><jats:sub>P</jats:sub> in terms of the strain-hardening modulus <jats:italic>E</jats:italic><jats:sub>P</jats:sub>. The true hardness <jats:italic>H</jats:italic> as a measure for plasticity is estimated from the Meyer hardness <jats:italic>H</jats:italic><jats:sub>M</jats:sub> and then successfully related to the yield stress <jats:italic>Y</jats:italic> as <jats:italic>H</jats:italic> = <jats:italic>C</jats:italic>(β,μ) × <jats:italic>Y</jats:italic> for elastic-perfectly-plastic solids and as <jats:italic>H</jats:italic> = <jats:italic>C</jats:italic>(β,μ) × <jats:italic>Y</jats:italic><jats:sub>R</jats:sub> for strain-hardening solids, by the use of a β- and μ-dependent constraint factor <jats:italic>C</jats:italic>(β,μ) ranging from 2.6 to 3.2.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382544420174559488","@type":"Researcher","foaf:name":[{"@value":"M.
