Abstract:

An analysis of fatigue crack growth and stable crack growth using the J-Integral has been carried out. At low and medium stress intensities the crack growth process appeared to be strain-controlled crack-tip blunting mechanism. however, at high stress intensities the growth was caused by void coalescence and the stable crack growth was derived from JB- curves. Assuming that these two crack growth mechanisms may act simultaneously and are additive, under elastic-plastic conditions, the total fatique crack growth was predicted.
