4. Discussion The presented research has the aim to review to possibility to perform a fatigue analysis for a multiaxial stress situation including fretting. The results show significant differences for the load cycles to crack and the crack initiation location. The load cycles to crack are much too low in the simulation model. More meaningful is the finding that the simulation model cannot predict the correct crack initiation location for the preloads 110 kN and 225 kN. In the experiment it is in the fretting zone and in the simulation model at the borehole. Overall, it can be stated that it is not possible to perform a fatigue analysis for this multiaxial stress situation with the methods implemented in the commercial solver. This is a meaningful gap for future research. Methods which take multiaxial stress situations with a dominant stress in thickness direction and fretting into account seem to be necessary to handle this load situation.
