Abstract Scope |
Many lab-scale analysis methods used in in-situ mechanical testing are capable of capturing fine surface microstructural details and their evolution during deformation. However, the subsurface evolution of the microstructure is unknown. This complicates direct comparison with crystal plasticity simulations except in the simplest cases of single crystals or oligocrystals. Several methods exist for generating statistically equivalent 3D microstructures from 2D surface data, however they typically do not retain the exact surface microstructure. Here, we introduce a Potts Monte Carlo based method to generate 3D microstructures from 2D surface data that retains the exact surface structure. The method allows for the direct comparison between experiments and 3D simulations for equiaxed, polycrystalline microstructures. Many instantiations of 3D microstructures will be generated for a surface structure to quantify the variability introduced by subsurface features.
