fatpack provides functions and classes for fatigue analysis of data series.
fatpack provides functionality for fatigue analysis based on stress-life damage accumulation methodology and includes rainflow cycle counting, fatigue endurance by SN-curves, mean and compressive stress range correction and racetrack filtering for accelerated fatigue testing.
Added options to also return the mean of rainflow ranges in the find_rainflow_ranges functions. Refactored endurance module, changes should make it easier to define BiLinear and TriLinear endurance curves.
This release introduces the new racetrack filtering module for removal of small amplitude cycles in the time series.
Bug fix: TriLinearEnduranceCurve.get_stress now correctly returns fatigue limit stress Sl
