摘要
The PRISMS-Fatigue open-source framework for simulation-based analysis of microstructural influences on fatigue resistance for polycrystalline metals and alloys is presented here.The framework uses the crystal plasticity finite element method as its microstructure analysis tool and provides a highly efficient,scalable,flexible,and easy-to-use ICME community platform.The PRISMS-Fatigue framework is linked to different open-source software to instantiate microstructures,compute the material response,and assess fatigue indicator parameters.The performance of PRISMS-Fatigue is benchmarked against a similar framework implemented using ABAQUS.Results indicate that the multilevel parallelism scheme of PRISMS-Fatigue is more efficient and scalable than ABAQUS for large-scale fatigue simulations.The performance and flexibility of this framework is demonstrated with various examples that assess the driving force for fatigue crack formation of microstructures with different crystallographic textures,grain morphologies,and grain numbers,and under different multiaxial strain states,strain magnitudes,and boundary conditions.
