Lattice Theory of Fourth Order Elastic Constants of Primitive Lattices

Abstract

The lattice theory of fourth order elastic constants for primitive lattices derived by S.C. Goyal and K. Kumar [3] is applied to obtain the relations for the FOE constants of NaCl structure types solids within the framework of the Lundgvist many body potential the drived relations of FOEC are used to compute the numerical values of the FOE Constants and second order pressure erivatives of the SOE Constants of Rubidium halide solids.
