Schwingfestigkeitsbewertung von additive gefertigten metallischen Bauteilen

A wide range of evaluation concepts exists for assessing the fatigue strength of metallic components produced in classical processes such as casting or welding. In these concepts, the mechanical and geometric properties can be taken into account for the fatigue assessment. In this paper, approaches for the transfer of known evaluation methods for the fatigue assessment of additively manufactured metallic samples are discussed. Therefore, the influencing variables relevant for the fatigue strength are shown. This is followed by a discussion how these variables can be taken into account for a fatigue assessment.
