I don't believe this argument applies to a joint consisting of a single
bolt, considered in isolation.

Thanks for an interesting discussion. This is what I come to RCM for!

Since you've put some thought into this, you may find that reading a more
sophisticated engineering treatment of it would be worth your while. It's
too far in the past for me to remember much of it but there is plenty of
material on ductility and brittle failure in the field of aerospace
engineering. It's a very big issue there.

I'm definitely interested in doing some reading. I'm building a small
library of engineering books at the moment.

You could try the SAE website, which has a bookstore and white papers in
the aerospace division.

Pardon the messy line wrapping - just wanted to show what's there...

Astronautic Structures Manual (On-Line), NASA MSFC (Marshall Space
Flight Center), 1975...

That looks like a really useful set of books. I'd like to get a copy of
those. Anyone got a set they'd like to sell?

Cripes, there goes the next three years of spare time. g

Thank God for FEA, eh? I used to try to optimize spaceframe structures by
hand. I spent most of a year, when I was 18, trying to optimize a little
Lotus-type frame that I designed, using a slide rule and paper. Now I can
change an element or two and run the whole stress/strain analysis in less
than 30 seconds. And if I spent serious money on the software I could even
let the program do the optimizing for me.

However, you still have to know what it is you're analyzing. You have to be
able to look at a design and smell where there could be trouble.

Indeed. That's where I'm building my knowledge at the moment.

Thanks for an interesting discussion!
