Rainflow. rainflow is a Python implementation of the ASTM E rainflow cycle counting algorythm for fatigue analysis. No dependencies beside Python's standard library. Supports both Python 2 and 3. Installation pip install rainflow Usage. Let's generate a sample time series of some load. I've been asked to use a rainflow counting algorithm for a project I'm working on. Does anyone have any experience of libraries that I could use for this task. I'm already calculating a number of other statistics using Python and Numpy, so any suggestions using / extending these tools would be ideal. The rainflow-counting algorithm (also known as the "rain-flow counting method") is used in the analysis of fatigue data in order to reduce a spectrum of varying stress into a set of simple stress reversals. Its importance is that it allows the application of Miner's rule in order to assess the fatigue life of a structure subject to complex loading.
