Cleaning corrosion - Thickness limit
Cleaning corrosion - Thickness limit
(OP)
I have to determine the maximum thickness than can be removed when using sandpaper for cleaning corrosion in some structure.
Does anybody know some bibliography or references about this issue?
No one of my work mates knows how to cope with this.
I assume that we could recalculate the structures imposing the minimum safety margin that we want to assure and find the new thickness with this condition. But it's only my supposition. We don't know if there's any standard procedure.
Any kind of help will be highly appreciated.
Thanks

Oexen, the structure is the engine pylon of a large aircraft.
SparWeb, the problem is that we are modifing the original aircraft, so the original SRM is not applicable. We have to substantiate new limits for the modified structure.
Anyway, we'll take a look at the original SRM.
What I expected to found is some information or standard method about this topic in books like Bruhn, Niu or any other that you may know.

You should have a look in the ACD's for the minimum reserve factors of the pylon and the coresponding load cases. With this data you should be able to recalculate the minimum thicknes (from static point of view).
Keep in mind that you will need a fatigue evaluation and as mentioned above design requirements.
