It provides:

• 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 CycleCount results 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 CycleCount instances
• 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.

Installation requirements

Py-Fatigue requires Python 3.8 or higher. It is a 64-bit package and it is not compatible with 32-bit Python.
