Countersunk holes

Countersunk holes

(OP)
Hallo,
I am studying a problem about fatigue growth of corner cracks at countersunk holes with and without rivets under membrane loading. Do you know where I can found any information on how it is possible to calculate the stress intensity factor K?
Any help will be appreciate.

RE: Countersunk holes

The effects of a countersink on the stress intensity factor are extremely localized, and have no effect on crack growth for a .050 initial flaw size normally used in analysis for the Air Force and FAA.

That being said, there are some good reports available on the web:

www.tc.faa.gov/its/worldpac/techrpt/ar95-111.pdf
techreports.larc.nasa.gov/ltrs/PDF/tp3192.pdf
research.faa.gov/aar/tech/docs/techreport/98-37.pdf

RE: Countersunk holes

I agree with Philcondit, the effect of the countersink is small. By the way, the book of Peterson will give you stress concentration factors, not stress intensity factors.
For stress intensity factors you can start with the book by Rooke and Cartwright; there are others too.
