Abstract Metallic sealing rings made from nickel-based superalloys are critical components of aero engines that
prevent the leakage of high-pressure liquid or gas fuel. As one of the main failure modes, fatigue cracking
has been a concern for the aerospace industries because the formation of even a micro-crack may cause an
aviation accident. For the purpose of manufacturing fatigue-resisting sealing rings, much effort has been
spent on the lifetime predicting under fatigue loadings. However, the fatigue analysis of metallic sealing
rings is challenging due to several aspects. On the one hand, the diameter of the rings (>100mm) is orders
of magnitude… More >
