This dataset includes initial EBSD maps of the Magnesium Rare-Earth alloy, SEM-DIC datasets with displacement and strain maps for a given Field of View (FOV), and Crystal Plasticity Finite Element simulations of the strain field, slip and twin activity for the same FOVs by setting up a Boundary Value Problem (BVP) with same boundary displacement conditions as the experimental data. The simulations have been performed using the PRISMS-CPFE code. The experimental input displacement and strain maps are in .mat format, readable by programs such as Matlab. The output files are in the *.vtu format, readable by programs such as VisIt and ParaView. Details regarding the simulation and characterization methods can be found in the linked paper.
