Va. Lubarda, NEW ESTIMATES OF THE 3RD-ORDER ELASTIC-CONSTANTS FOR ISOTROPIC AGGREGATES OF CUBIC-CRYSTALS, Journal of the mechanics and physics of solids, 45(4), 1997, pp. 471-490
An improved method, based on an extension of the self-consistent metho
d from the linear theory, is proposed to evaluate the effective third-
order elastic constants for isotropic aggregates of cubic crystals. Th
e calculated constants are compared with the Voigt and Reuss-type esti
mates, which are currently the only other analytical estimates availab
le for these constants. The agreement between calculations and experim
ental data is then discussed. (C) 1997 Elsevier Science Ltd.
