Fatigue crack growth in notched specimens: a numerical analysis

open access: yesFracture and Structural Integrity, 2019
Fatigue crack growth (FCG) is linked to irreversible and non-linear processes happening at the crack tip, which explains different problems observed in the use of da/dN-?K curves. The replacement of ?K by non-linear crack tip parameters, namely the crack
