Abstract
Fatigue design of components subjected to cyclic loading requires special testing methods, component related material data and an appropriate safety concept. The following contribution presents a newly developed methodology for the fatigue design and testing of highly loaded ceramic components. This methodology is verified by laboratory and in-service testing of Si3 N4 intake and exhaust valves.
