Abstract
The main objective of the DMR system presented in the work is to create the digital microstructure with its features (grains, sub grains, grain boundaries) represented explicitly. Particular attention in the paper is put on designing three dimensional DMR. These digital structures are used to generate finite element meshes that exactly replicate geometry of grains. Finally obtained meshes are used during simulation of the deformation process to analyze stress concentration along grain boundaries. Details of implemented algorithms are presented in the paper. The advantages and disadvantages of this approach are discussed, as well.
