Welcome to, the home of Fatlab – a free open source fatigue analysis software developed in Matlab.

Fatlab works by postprocessing results from FE analyses and combining these with load-time series in order to perform a detailed fatigue assessment of a component. It handles both multiaxiality (through the critical plane method) and non-linear FE models.

Fatlab was developed at Aalborg University by M. M. Pedersen in collaboration with R&D A/S. It is part of the project “Wind load simulator for function and durability test of wind turbine drive-trains” and has been partly sponsored by the Danish Energy Technology Development and Demonstration Programme (EUDP) .
