Ongoing efforts in development of novel analytical methodologies to perform detailed simulations of polycrystalline alloys at the microstructural levels provide new opportunities for material development and life assessment processes. Examples of such methodologies start with microstructure reconstruction via measurement or prediction, and generation of associated FE mesh. Once the grain structure is captured by the FE model, detailed analyses can be performed using crystal plasticity methodologies that are validated both at the single crystal and polycrystalline levels. Such analysis can be combined with experimental observation of local damage to help better understand the grain level crack nucleation process. The purpose of this paper is to demonstrate some of the efforts and describe opportunities and challenges in this area.
