Py-Fatigue is a Python package for cycle-counting, fatigue analysis and crack propagation prediction. It is developed by OWI-Lab at Vrije Universiteit Brussel. Full documentation can be found here.
The main features of Py-Fatigue are:
- a powerful cycle-counting implementation based on the ASTM E1049-85 rainflow method that retrieves the main class of the package:
CycleCount - capability of storing the
CycleCountresults in a sparse format for storage and memory efficiency - easy applicability of multiple mean stress effect correction models
- implementation of low-frequency fatigue recovery when "summing" multiple
CycleCountinstances - fatigue analysis through the combination of SN curves and multiple damage accumulation models
- crack propagation analysis through the combination of the Paris' law and multiple crack geometries
- and more...
Py-Fatigue is heavily based on numba, numpy and pandas, for the analytical part, and matplotlib as well as plotly for the plotting part.
Therefore, it is highly recommended to have a look at the documentation of these packages as well.
