IKAT has successfully published its research results on estimating the survival probability of shafts in the renowned paper ‚Engineering Failure Analysis‘. We would like to thank Dipl.-Ing. S. Vetter for his excellent research work in the group WNV/Strength and congratulate him on the publication of the research results. Herein, a proposal is given for estimating the survival probability of shaft-like components in the HCF and UHCF range.
