Abstract Scope |
The open-source PRISMS-Fatigue framework is a highly efficient, flexible, scalable, and easy-to-use ICME community platform. Computed Fatigue Indicator Parameters (FIPs) serve as surrogate measures of the driving force for fatigue crack formation. We demonstrate the efficacy of the multi-point constraints available in PRISMS-Fatigue to impose periodic boundary conditions in microstructure-sensitive crystal plasticity finite element method simulations. The extreme value driving force for fatigue crack formation is compared using various boundary conditions, microstructures, and crystallographic textures. The effects of both periodic and non-periodic applied boundary conditions on different mechanical responses such as the macroscopic stress-strain response, local measures of plastic slip, and corresponding FIPs are studied. The results provide guidance for microstructure-sensitive crystal plasticity fatigue studies and demonstrate the advanced capabilities of PRISMS-Fatigue to model large volumes of material microstructure. |
