The crack front was approximated by a spline curve. In each node defining the crack front the stress singularity exponent has been estimated and complete crack front shape was found. The difference between thin and thick specimens is described and discussed. The methodology presented can help to estimate crack front shape in a linear elastic fracture mechanics framework and estimate fracture parameters of cracks more accurately. Therefore, the results presented can be helpful for a better understanding of fatigue failure and more reliable prediction of their residual lifetime."@en .
