Do you guys think the Titan blew up down there day of and its just taken this long for everything float back up?
If it imploded, the only things that are going to float back up would be exterior objects that were either buoyant or inherently hollow but high strength: Maybe an LED light or similar? MOO and Depends on how the periphery items came apart...
Did a little look into Titanium and Carbon Fiber. Titanium has about the same tensile and compressive yield strength as the better stainless steel alloys but is 40% of the weight, per unit volume. Problem is: its brittle at its ultimate strength. Carbon Fiber can be a made a lot of different ways but essentially consists of high strength fibers bound by some polymer; and weighs about 18% of steel. Either material is "elongation brittle" in material terms: carbon fiber samples fracture at around 3 to 4% strain and high grade titanium at less than 3%.
SO: Here's how a ductile (Mild Steel) horizontal cylinder implodes at low pressure differences....pretty quick for the cylinder portion, the heads at each end near survive. Consider though: when the collapse occurs, the reduction in volume of the containment would cause the internal pressure to increase, thus the pressure difference decreases....
With the infinite volume and depth of the ocean: the rise in internal pressure would occur in the order of 1/900 of a second and with brittle material, the cylinder would collapse inward and fracture. Should it occur that there was some air trapped at one spot, there would be a second collapse as that air pocket condensed...presuming the hull was ruptured by the first collapse, the pieces may or may not be dislodged or otherwise effected by the second collapse.
I would guess thought that some pieces of carbon fiber would be projected and spread around. Whereas I believe the titanium heads may be distorted but largely recognizable.
MOO and I'm sure some images will be forthcoming.
