Difference between generalized and localized cracking
Difference between generalized and localized cracking
(OP)
The question may be stupid, but I cannot find any clear definition of both generalized and localized cracking.
Does anybody know the difference, preferably in aircraft structures?
Thank you.

RE: Difference between generalized and localized cracking
generalised cracking is several cracks reasonably close together, or multi-site damage. typically initiated by fatiguing many small (minor) flaws that are replicated at many sites (ie typical manufacturing quality).
RE: Difference between generalized and localized cracking
May I say that cracks found in a joint or fitting (where we have significant load transfer from fastener to fastener) are localized, while cracks found at a wing skin panel spanwise splice (load transfer is almost zero) are generalized in terms of the wing fatigue life?
Or you think my interpretation is irrelevant?
