 ## Purpose
-`FFPACK` ( Fatigue and Fracture PACKage ) is an open source Python library for fatigue and fracture analysis. It supports the load cycle counting with ASTM methods, load sequence generators, fatigue damage evaluations, etc. A lot of features are under active development. `FFPACK` is designed to help engineers analyze the fatigue and fracture behavior in engineering practice.
