... tips. The relatively high crack growth rate may be caused by MnS inclusions. The loading rate, dJ/dt, was calculated for each crack condition in order to correlate qualitatively the crack growth rate with the loading rate. J-integral was calculated through non-linear FEM analyses for semi-elliptical...

... 07 10 2008 Fatigue life assessment procedures require knowledge of the fatigue crack driving force, such as stress intensity factor range (Δ K ) and cyclic J -integral (Δ J ), for the flaw geometry detected during inspection. Because three-dimensional closed-form crack driving force...
