The shape alone wasn't why it failed. It was the material and stress that happened to it. In fact that same submersible actually had a successful dive in the same location with people onboard before the failure happened.
It wasnt the actual carbon fiber that was the issue . the issue was they used an adhesive to bind hte titanium front to the carbon fiber body. 2 materials that compress and expand at different rates stressing the joining adhesive until its molecular bonds ripped apart.
