摘要: Abstract In Part 1 of this work, ample experimental evidence was presented uncertainty in the fracture mechanics characteristics environmentally assisted cracking. This paper addresses soundness approach to phenomenon — K -dominance over all process constituents and reveals intrinsic variability crack growth kinetics curve v = ( ) threshold stress intensity factor th . Suggestions consolidate by a strictly local treatment are outlined procedure is proposed for engineering safe design against cracking based on idea worst tip situation as one material-environment system.
