Currently in beta testing - comments welcome. Beta testing means the package is working and stable but my test suite isn't totally complete, and I don't my examples or documentation finished.

Hysteresis: Tools for Non-functional curves.

Hysteresis is a library of tools for non-functional curves, with a emphasis on force-deformation hysteresis curves. While functions only have one direction, non functional curves change direction, making analyzing them difficult. Some key features of the library include:

• Finding peaks or reversal points in data.
• Numerically finding the slope or area of a curve.
• Resampling curves.
• Comparing Hysteresis made with simialar load protocols.

Basic Demo

A basic demo of the hystresis object. Hysteresis can split up a non-function into a number of cycles that are functions. This allows them to be analyzed more easily or compared with other hystereses.

Install

Hysteresis is pip installable via:

pip install hysteresis

Features

Using Hysteresis, it's possible to:

Find peaks

Find cycles:

Find energy in a hysteresis:

Down sample a hysteresis:

Terminology

A SimpleCycle is Curve that is a function, that is, each x value is paired with a single y value. The term "Cycle" is a little nebulus, as it implies that we return to where we started.

A MonotonicCurve is a Curve that only increases or decreases
