The Elastic Stiffness Moduli of Diamond

Abstract

Estimation of elastic moduli and bending stiffness of the anisotropic outer hair cell wall Fourth order elastic moduli of diamond structure materials

Raman spectroscopy on carbon nanotubes at high pressure

“…In the second place, they claim that the shear-deformation treated SWNTs have a bulk modulus of 462-546 GPa, larger than that of diamond (442-446 GPa). 74,75 Besides the fact that a large bulk modulus is not a sufficient condition for high hardness, 76 the claim turns out to be untenable in view of the available experimental data.…”

Second-order and third-order elastic properties of diamond: An ab initio study

“…b Ref. [21]. c The value of the shear modulus G is the arithmetic average of the Hashin-Shtrikman quasi-isotropic polycrystalline upper and lower bounds [31,32] reported in Ref.…”

Nanoindentation of glass wool fibers

“…The E i and m i are, respectively, the elastic modulus and Poisson's ratio of the diamond indenter (E i = 1140 GPa, m i = 0.17 [23][24][25][26][27]). …”

“…Let us begin by denoting the indenter as body '1' that is made from polycrystalline diamond (thereby ignoring orientation effects of the single crystal indenter) with an elastic modulus, E 1 , of 1140 GPa and a Poisson's ratio, m 1 , of 0.17 [23][24][25][26][27]. For the purposes of this analysis, we will approximate the Berkovich tip by an 'equivalent sphere' that has principal radii, R 1 and R 0 1 ; that are the size required for a sphere that would have the same projected contact area as the Berkovich geometry at the penetration depth of interest.…”
