Re: pic: 20's IRI Carnage
I was curious about this failure, so I pointed a more knowledgeable person to this thread. His suggestions:
Quote:
-Without a small radii at the corners, there are huge stress risers at all of the corners.
-The cross section at the bolt hole is extremely small, and the stress concentration here will be extremely high.
-It would be interesting to try Ti for this part.

It is possible that the radi on the AM dog is larger than the WCP dog, which contributed to the failure. I can't tell from the pictures.
