Suggestions for a fastener / joint analysis textbook? (For aerospace applications)
(OP)
I spent 20 minutes searching on google and another 15 searching here, but I can't seem to find a book that details all reasonably conceivable fastener failure modes (particularly for aerospace applications), and how to calculate margins for them. I'm aware that companies all have their own proprietary manuals that they use, and I'm aware that they build these manuals using a variety of texts such as Shigley's Mechanical Engineering Design, but I was hoping that there is a fastener / joint analysis textbook or handbook out there that lays out fastener analysis clearly and thoroughly.
Anyone have any suggestions?

I do not believe Bruhn or Niu cover bolt preloads and joint stiffness analysis. If that is not a concern, then ignore my response.
However, installation torques introduce some high preloads that must be combined properly with the applied loads. There are several authors
that cover this subject… Shigley, 3rd Edition was the best presentation I have seen.
Now when I was recently working for MSFC on huge rocket sections which are bolted together, the requirement have to meet the following criteria:

Of course NASA does everything on a grand scale, so you might want to tailor the document to meet you criteria and create EXCEL spreadsheets.
Have fun.

I like to refer to MIL handbook 60 for torque / tension rations for common bolts in common installation scenarios.
Great reference from Grandpa, too.

With regards to friction at a clamped interface due to fastener preload, whether or not this is considered in terms of shear capacity is a topic of some debate. I design mechanical systems, and it is common to rely on friction at a clamped interface from fastener preload to transfer shear forces. The reason for this is that often it is not practical to design highly loaded component interfaces using large numbers of shear fit fasteners due to interchangeability requirements. On the other hand, in my experience the structures guys always ignore friction due to clamped preload, and put all of the shear thru the fastener bodies.
Regardless of which analysis approach you use, both friction and gapping at a shear interface are important concerns due to the potential for fretting at the joint contact surfaces. If there is even the tiniest amount of sliding motion at the shear interface fretting damage will likely occur.
While most text books will give you an analytical approach, what you also need are the various Factors of Safety required for your analysis. These analysis factors are normally defined in a design requirements document, and they can vary substantially from program to program.

There are failure modes explicit to each major fastener type.
permanently installed straight-shank bolts/nuts/washers
permanently installed taper-shank bolts/nuts/washers
frequently removed bolts/screws in nuts or nutplates
permanently installed swaged-collar lock-bolts
permanently installed threaded collar lock-bolts [Hi-Lok style pins/collars]
permanently installed solid rivets
permanently installed blind rivets
permanently installed blind bolts
threaded inserts [solid or helical coil, etc] with bolts/screws in wrought or cast materials
non-threaded inserts [bushes, etc]
etc, etc...
All fastener-related failures are aggravated by general factors such as...
undetected manufacturing process flaws/errors.
improper storage and transportation.
structure induced damage due to initial poor fastening practices.
structure induced damage due to in-service fastening problems [corrosion, fretting, fatigue cracking, stress corrosion cracking,etc]
improper design methodologies for specific structure types.
localized fastener overload [shear, tension] in-service.
general structure overload [shear, tension, compression, etc] at fasteners, and fasteners HOLES.
environmental damage [corrosion, embrittlement, etc] to the fastener and/or the surrounding structure/hole.
etc, etc...

Anyway, some folks, at NASA for instance, are making an entire career on this subject matter.
It's like trying to prove analytically that if a string has one end then it has another. Would you
spend your entire life on this subject?
