ISODEC: software for calculating diffraction elastic constants

A program is introduced that calculates diffraction elastic constants for the Reuss, modified Voigt, Hill, Kroner and inverse Kroner models. For materials with preferred orientation it uses the orientation distribution function (ODF) to calculate the anisotropic stress factors. The ODF is read in text format as output from the freely available texture programs popLA and MTEX. The software also calculates the orientation-dependent mixing ratios of intensities of overlapped reflections, anisotropic bulk constants, and stress from lattice strain and vice versa.
