... for this analysis. This solution assumes that cracks have a circular arc crack front whose aspect ratio starts as 1.0 for small cracks. As the crack propagates, the aspect ratio changes according ... experimentally. The approach was to subtract the crack propagation time from an initial crack size a 0 from the total life to failure, where a 0 is the transition crack size in the Kitagawa...
