Abstract [en]

In this work, three different series of fatigue experiments on INCONEL718 will be discussed. For each type of fatigue experiment, the method of evaluation the raw data obtained at the matrial laboratory will be mentioned. Morover, from the obtained results, the fatigue properties of INCONEL718 will be presented in detail. Subsequently, a discussion of the modeling of the fatigue properties of the material in an isothermal condition will be permormed. For that, three different type om models will be investigated and compared. Furthermore, a FEM model of a specific specimen used for TMF-testing (not to be discussed here) will be presented by which the stress intensity factor values can be evaluated.
