I've seen a lot of posts lately, regarding the dilivar stud failures (and of course I've read Wayne's book, with regards to same) - I've got a question - Has anyone done an "autopsy" on some of these failed studs, to try to discover the root cause?
I know that there are many different failure modes for metals, but I've NOT ever heard of anyone doing the material science on these parts. (could it be hydrogen embrittlement, for example?)
Do we have any such expertise in the PP "brain trust"? If so, can we find one expert (or willing amatuer) who would perform some analyses on some failed studs?

I would think that some Pelicanites who have connections with universities or research labs, may be able to shed some light on the failure mechanism of these parts. It would make a decent 'senior project' for an aspiring materials science or mechanical engineering student...... what say you Pelicanheads? Any volunteers? I'll submit the first set of samples.

If we an understand the cause of the failures, then we could go about making informed decisions about what studs to use, and why.
