This data set contains the simulation input files and raw simulation results for the manuscript entitled "Crystal plasticity finite element modeling of grain size and morphology effects on yield strength and extreme value fatigue response". The Three folders entitled "Calibration", "Fatigue", and "Hall-Petch" each contain a "ResultsFiles" and a "SimulationFiles" folder. The "PRISMS-Plasticity_SourceFiles" folder contains the unique files to include grain size and morphology effects in CPFEM simulations.

There are two Python scripts available at the PRISMS-Fatigue GitHub page (https://github.com/prisms-center/Fatigue) in the "applications" folder that will generate the some of the results plots of this manuscript. These two scripts are entitled "grain_size_effects_max_PSSR.py" and "grain_size_effects_compile_FIPs.py.py". These two scripts should be placed in the "ResultsFiles" directory in the "Fatigue" directory, i.e., "Fatigue\ResultsFiles". Using a command prompt window, users will then navigate to the directory that contains these folders and two Python scripts. Users will then execute the command "python grain_size_effects_max_PSSR.py.py" or "python grain_size_effects_compile_FIPs.py.py" to run the scripts. The scripts can also be executed using an interactive version of Python.
