“…He concluded that the effect of friction is small for indenters with a large angle (like Berkovich and Vickers) and this effect is more significant when the angle of the indenter (θ) is less than 60°. This result was also reported by Bucaille et al [22] and Kojima et al [25].…”

“…Indeed, as mentioned by Liu et al [15], Bucaille et al [22] and Bocciarelli et al [23], when the coefficient of friction is greater, the height of the pile-up patterns decreases. Even though the friction influences the patterns near the indented imprint, this coefficient is generally considered to be "zero" by many authors.…”

“…It should be emphasized that the representative strain defined in the Tabor equation is an average value. The strain constraint fact, , should vary with the depth of the indentation for which the tangent of corresponding contact point could be equal to the same angle of sharp indenter [6,55]. Most of researchers agreed with the formulation of Tabor's equation, but argued the choice of the value of  and  [56][57][58][59][60][61][62].…”

“…It should be emphasized that the representative strain defined in the Tabor equation is an average value. The strain constraint factor,  , should vary with indentation depth through which the tangent of the corresponding contact point can be equal to the same angle of a sharp indenter [6,55]. The fact is that the equivalent stress and strain at an arbitrary point beneath the indenter should be equal to the uniaxial stress strain curve from the result of FEM, although the equivalent stress and strain of the material vary from point to point [75,146] .…”
