✦ Synopsis

Ah&act-Fatigue crack growth data in the region of stage II(a) and stage II(b) have been attempted. It has been observed that the stage II(a) and the stage II(b) crack growth rate vs AK relations have their own pivot points. The dependence of the threshold stress intensity factor on the stress ratio and temperature has been obtained in terms of the pivot point co-ordinates. The predicted values of the threshold AK compare well with the experimental data.
