Experimental evaluation of CTOD in constant amplitude fatigue crack growth from crack tip displacement fields [PDF]
In the current work an experimental study of the crack tip opening displacement (CTOD) is performed to evaluate the ability of this parameter to characterise fatigue crack growth.

Fatigue crack growth in notched specimens: a numerical analysis
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
