Plot of ½S2 under Reuss, Voigt, Neerfeld and Kröner limits for Cu as a function of Γ. xKr is depicted graphically as the ratio of to . All of these XEC intersect at approximately Γ = 0.276, corresponding to the vertical dotted line. The single crystal elastic constants of Cu (from Ref. 22 ) can be found in Table I .
(a) Weighted Reuss-Voigt fraction values, xKr, for various materials possessing cubic elastic symmetry plotted as a function of the anisotropy factor, A = 2 CC 1212/(CC 1111-CC 1122). Single crystal elastic constants were obtained from Ref. 22 ; (b) linear fit of weighted Reuss-Voigt fraction values for A < 5.
Weighted Reuss-Voigt fraction values, xKr, for various materials possessing cubic elastic symmetry plotted as a function of the dimensionless parameter, Q = (CC 1111-CC 1122)/(CC 1111 + 2CC 1122). The asymptote 5/9 corresponds to the case of Q → ∞ and C2 ≪ C1.
Plot of the weighted Reuss-Voigt fraction, xKr, of ½S2 for Ti as a function of the orientation parameter, η2, where squares correspond to specific (hkil) reflections. The continuous curve corresponds to values calculated using Eq. (23) .
Plot of the Voigt, Reuss and Kröner limit ½S2 values for Ti as a function of η2, where the shaded portion delineates the range of η2 in which the Kröner XEC lies inside those under the Voigt and Reuss limits.
