Material database with fatigue strength data for calculation and construction. To realise product development in shorter and shorter times and with the highest quality, release with the manufacturers a rising time pressure and cost pressure. Under these requirements FEA and simulation calculations take a dominant role for the security of the load corresponding component engineering and dimensioning. As input values reproduceable, reliable data and information are necessary for the fatigue strength behaviour, which are quick available and uniform represented. The contribution introduces outgoing from the requirements relevant for practise for the life prediction and the role of the fatigue strength a complex material database with a fatigue strength behaviour module.
