Holes mismatch fatigue effect
Holes mismatch fatigue effect
(OP)
The practice of copying existing holes from structure to repair parts like doublers or splices is used as standard.
Although it is assumed that the holes are completely aligned if you use guide bushing to transfer them between parts, if you take into account clearance between bushings and hole and btw. drill bits and bushing it is clear that there could be some mismatch between existing and repair parts holes.
I´m trying to find any reference that could help me evaluate the effect of that mismatch in the behavior of the structure, specially from the fatigue POV.

If we consider a situation where we have to discard all other options and have to live with the same size fastener (our situation), up till now I haven't been able to find any reference to help me determine the fatigue effect of the mentioned mismatch.

I pulled the document from DTIC and its free compliments of the US tax payer. It's too big to post but I attached the cover page for your reference. You might have better luck searching by the ADA number
