@wgowshipping On your next video you should highlight the failure test of carbon fibre and glass fibre hulls that Carl Ross posted 10 years ago. He posted 2 videos titled Collapse of Composite Submarine Pressure Hulls Collapse of Carbon & Glass Fibre Tubes under External Hydrostatic Pressure. I have no idea who Carl Ross is (or was) but there's 2 things to note about those videos. 1) How sudden the failure is. If you look at how titanium fails its much like any other metal there's deformation eventually followed by failure. I am an engineer (aerospace) but did my first year in mechanical and we did that stuff in the lab. Most of the failure videos of things being crushed or bent in a hydraulic press show that but they also often show the sudden failure of carbon fibre composite materials. So you and other are most likely right the people in Titan probable had no warning it was all about to fail other than hearing a lot of cracking. 2) the Carl Ross videos show very little damage to the Carbon fibre tube other than what looks like a crack down the side. What people need to understand is that it was done in a small pressure test rig NOT the open ocean so there was very little water to keep applying pressure once the tube failed. I have done work in the petro-chem industry and other places where they pressure test pipes with water. If something does let go during a hydrostatic test there's no explosion of water because its incompressible. That test cell Carl Ross used has very little water in it so there's not a lot of volume to rush into the test model and do lots of damage. It just had enough water to break the cylinder.
