Oxide-induced crack closure and its implications for lifetime prediction of mechanical components (OXILAP) (GA22-28283S)

The impact of oxide-induced crack closure (OICC) on a fatigue crack propagation threshold will be studied. The oxide formation on new crack surfaces significantly influences crack closure and is also respo...

Effect of Impurity Embrittlement and Microstructurally Induced Shielding on Crack Stability and Growth Resistance in Low Alloy Steels (OC 517.30)

evaluation methods, however, completely ignore the micro-tortuosity of the crack front.Related shielding effects might substantially reduce the real crack driving force in comparison with the standardly assumed straight crack
