It is important to know the relationship between the elasticity constant of single crystals C and E and the materials technical constants E, G and u.

For an isotropic aggregate, the stiffness averaging procedure had been proposed by Voigt, ° and the compliance averaging procedure by Reuss, many years previously. Each had been used to compare the elastic constants of single crystals with those of an isotropic aggregate of single crystals (see for example Ref. 12). 

The room-temperature elastic constants of single crystals with the stoichiometry B5 fiC synthesized by the optical floating zone method have been measured using a resonant ultrasound spectroscopy technique [531]. The single crystal elastic constants indicate the strong anisotropy of the structure Cn = 542.81, Cg3 = 534.54, Ci3 = 63.51, C12 = 130.59, and 44= 164.79GPa, respectively.
