Residual stress, fatigue and stress relief

I think jim's point is that no-one has shown that spoke fatigue starts
on the inside of the bend significantly (or at all) more often than it
starts on the outside.
"jim beam" doesn't correct his spoke lines. He will have a moment under
normal load. That will likely be larger than any residual stress
contribution.
The evidence we would expect to see for residual stress being a factor
just isn't there.
Having said that many people (who aren't jim beam) don't scrutinize the
broken spoke carefully through a magnifying glass, but just chuck it in
the trash, so we wouldn't know.
People like Jobst & I are at a disadvantage from a "forensics" angle --
we don't break spokes, so have no samples to analyze. "jim beam" seems
to have plenty. Follow his faith-based analysis if you want.
