pyLife – a general library for fatigue and reliability¶
pyLife is an Open Source Python library for state of the art algorithms used in lifetime assessment of mechanical components subject to fatigue load.
Purpose of the project¶
This library was originally compiled at Bosch Research to collect algorithms needed by different in house software projects, that deal with lifetime prediction and material fatigue on a component level. In order to further extent and scrutinize it we decided to release it as Open Source.
So we are welcoming collaboration not only from science and education but also from other commercial companies dealing with the topic. We commend this library to university teachers to use it for education purposes.

Disclaimer¶
pyLife is in continuous development. We hope to keep the interfaces more or less stable. However depending on the practical use of pyLife in the future interface changes might occur. If that happens, we probably won’t be able to put too much effort into backwards compatibility. So be prepared to react to deprecations.
