Abstract Scope A novel open source framework that enables simulation-based comparisons of microstructures with regard to fatigue resistance is presented here for polycrystalline metals and alloys. The framework uses the crystal plasticity finite element software PRISMS-Plasticity as its microstructural analysis tool. This framework provides a highly efficient, scalable, easily modified, and easy-to-use ICME community platform. The performance and flexibility of this framework is demonstrated with various examples, including effects of crystallographic texture, grain morphology, strain state, free surface effects, and choice of FIP on the driving forces for fatigue crack formation. The results show that the multilevel parallelism scheme of PRISMS-Fatigue framework is more efficient and scalable than ABAQUS for microstructure instantiations having over one million degrees of freedom. The links between the PRISMS-Fatigue and experimental characterization techniques and virtual microstructure generators are elaborated. PRISMS-Fatigue is also linked to the information repository of Materials Commons to store and share inputs and results.
