Abstract:
The fatigue behavior of additively manufactured parts is particularly influenced by process-induced inhomogeneities. These inhomogeneities are statistically distributed in parts. According to the statistical size effect, the probability of the occurrence of a fracture-inducing inhomogeneity is greater in a large part than in a small one. In this study, the influence of these inhomogeneities on the fatigue behavior of two different part geometries is investigated under rotating bending and tension-compression loading. For evaluation, models by Murakami, Kitagawa and Takahashi as well as Shiozawa are applied.
