AEH-EBSD Toolbox for the Thermomechanical Analysis of Polycrystalline Materials

Software – AEH EBSD Analysis Toolbox

The GUI software is a standalone interface for the thermomechanical analysis of polycrystalline materials using Asymptotic Expansion Homogenization (AEH). The AEH method, which uses a finite element mesh, provides accurate results since it explicitly accounts for grain-scale interactions. The user need only provide an EBSD data file in .ang or .ctf format, or an image of the microstructure, along with phase property files. The package contains a Matlab-based graphical user interface (GUI) which has been designed for ease of use and efficiency. Post-analysis options allow the user to plot microscale stresses and strains, as well as seismic wavespeeds via contour plots. Results can be exported with publication quality by using built-in Matlab functions. A basic user manual and tutorial video can be downloaded from the links provided below.

The GUI package is the result of a joint effort between the Mechanical Engineering Department (Alden Cook and Senthil Vel) and the School of Earth and Climate Sciences (Chris Gerbi and Scott Johnson) at the University of Maine. The coding was done in Matlab and C by Alden Cook.
