Microstructural Analysis of Bulk Elastic and Seismic Properties The GUI software is a standalone interface for the calculation of bulk elastic and seismic properties of heterogeneous and polycrystalline materials using image or EBSD data. The GUI includes a number of different homogenization techniques, including Voigt, Reuss, Hill, geometric mean, self-consistent and Asymptotic Expansion Homogenization (AEH) methods.  The
