摘要：

An improved method, based on an extension of the self-consistent method from the linear theory, is proposed to evaluate the effective third-order elastic constants for isotropic aggregates of cubic crystals. The calculated constants are compared with the Voigt and Reuss-type estimates, which are currently the only other analytical estimates available for these constants. The agreement between calculations and experimental data is then discussed. (C) 1997 Elsevier Science Ltd.
