[PSUBS-MAILIST] Titan submersible missing at Titanic site

[Jon Wallace via Personal_Submersibles]

 Thick accent and I'm not very familiar with FEA so perhaps someone can summarize in plain language.  What I got out of it was that the vessel was good for 100 mpa (megapascals) in terms of linear buckling and 57 mpa in material failure.  With a 25% safety factor the material failure drops to 42 mpa and Titanic sits in 40 mpa, very close to the failure point.  However, we know Titan didn't make it to Titanic on the ill-fated trip so it sounds feasible that cyclic pressure took it's toll on the carbon fiber hull or the transition area to the heads.
Anyone have more details they can share?
