Re: pic: 20's IRI Carnage
After looking at a bunch of material sheets, I agree with Cory. Stainless steel is actually quite weak compared to many alloys of non-stainless steel. I surprised myself here.
Why stainless was chosen instead of hardened steel for the AM part is then a question as well (unless it is a prehard stainless alloy).
Which brings us to component design failure. Either the design load was exceeded (possible, but then design load should be increased) or design was not properly analyzed (also possible, likely shock loading or fatigue not correctly estimated in that case).
Is this picture the first dog to fail or the second? If it was the second that might explain the failure more, as the hole was drilled larger, at the point of highest stress.
