Project

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...
