thanks for this good report, that was the best analysis i heard so far to the titan disaster, and i feel sorry for all the serious submarine builders which expertise is brought into question by some yahoo. i cannot understand how anyone could consider that fellow as a serious engineer (at least in diving). a vacuum vessel (which a submarine technically is) needs more than 10 times the wall thickness than a pressure vessel. and that under atmospheric conditions. i'm not a submarine expert, but i don't know of any diving container for humans that can go down 4000m and is not a perfect sphere anyway. ask james cameron, he knows, or at least listened to the experts..... if anyone is in cherbourgh, france, there is a very nice submarine museum in the harbor with loads of deep sea vessels, aquarium, a titanic section and much more.

Professor please forgive my ignorance, but could you see if a design like this could work if it we properly designed? Just a question from a layman.

Are you kidding? Read the damn thing yourself! Using ai readers is a cheap ass way of cutting your workload. If you have a thing to say then say it yourself.

Even this analysis is not complete without doing an analysis of the bonding agent between the titanium domes and the CFRP cylinder! That is even more critical and this video made some joke about it @11:06!!!

Worked ha ha

When i woref for a heat treater .we x rayed all sub parts .i guess rush had x Ray vision

As long as i imagine the voiceover was done by that beaver in "lady and the tramp" (the one that always whistled while he talks) this is watchable.

Thank you so much Prof. Wagner. I am dealing with FGM and UMAT, your tutorials really help me a lot.

wonderful!

I watched the Challenger Deep documentary after this happened and realized how much of a horrible design this was. Its unfortunate, his ego got everyone killed

as a science/engineering enthusiast this is the BEST disaster analysis I have ever watched on youtube. Ronald Wagner and his team are genius science explainers - kudos to you 🏆🥇⛑️💥🤯⭐️⭐️⭐️⭐️⭐️

watched a few videos like this but something that bugs me is why no one seems to be talking about the bond between the titanium & the carbon fiber, seems to be a obviouse failure point?

The thing is, that it was made in a pure LINEAR winding method not CRISSCROSS.

I'm subscribing just because of your ad lead in, and of course the meaningful interview with Stockton. Thanks for an entertaining and educational video.

I think we can all agree. DEI = DIE. Next time, hire scientists and engineers based on their skills, and not their skin and genitals

If this is the “world’s first”, how come I’ve already watched about five of these things? 🤔

That sub at the end? ... ... It uses anti-gravity?

Absolutely revolting. Millionaire hothead looking to make a name for himself, dragging other poor souls into his narcissistic fever dream.

You need to teach your AI the difference between the verb "wound" - to injure a living plant or animal, and the verb "wound" - the past tense (among other tenses) of the verb to wind.

My guess is the porthole was ejected the same time what was left of the occupants did. Virtually a tube of toothpaste.

Quasi iso layup? ~[0/90/90/90] no 45s at all. You're strength calcs are way low. I agree it was low cycle fatigue. They had strain gauges all over the inside of the hull to augment their acoustic sensors. That data if ever released would be very interesting

Remember when the CEO said publicly white males need not apply and hired based on a checkbox instead of qualifications?

I didnt expect the Stockton rush roast😂😂😂

Ashes to ashes, dust to dust.

hi, do you run your script in python? or do you copy it into abaqus and run it there?

The shear reinforcement area is adequate if you consider member 11 intersects the construction joint at 32 deg. thus significantly increasing the longitudinal rebar's contribution. The nodal block reinforcement also contributes to the total, not to mention misc. interaction with some member 12 rebar as member 11's force distribution broadens through the nodal block. David can't help you here.

Okay thank you for the video now read me a bedtime story.

People really... You are fighting with each other about what ❓ 🤔🤔🤔

Great video, especially the humor. Do we think that the reports of underwater “banging” noises detected up to days after the disaster may be attributed to larger fragments of the composite material succumbing to the pressure over time? It seems strange to think that *no* fragment of composite material would’ve survived the initial collapse, but it might be reasonable to think that over a little bit of time such debris would be turned to dust by the pressure and could’ve even generated loud and sudden noises as failed.

Presto! Strawberry Jelly! Water makes for a fantastic explosive lens. 1000kg of TNT (a blast in a confined space) with pressure waves bouncing back and forth inside that pocket of air (sans pressure hull) with the water compressing the bubble further and further every microsecond.. I doubt there is a better demonstration of the word disintegrate. It may be that only the hardest parts of their bodies survived. Perhaps some teeth or fragments of tooth enamel was ejected as exhaust within the first few compressions (in microseconds). Anything else with lower ignition thread holds would have been smoked and converted to ash. That blast or implosive force had nowhere outward to go surrounded by water, you need the gravity of a star to compress liquids and so there would be no yielding. Imagine that 1000kg TNT blast video shown here, instead being forced or confined into the volume of a minivan, ever shrinking in size to that of a body bag. Finally, the cavitation converted to tiny bubbles of carbon monoxide, cremated human remains and detris such as plastic and metal ash raining down all over the wreck site. I wouldn't wish this on my worse enemy, as they would never suffer

I didnt understand what you want to deliver? This hyperealstic calibration is the most difficult one! It is showing unstable in both modeling type, what do mean that?

That interview 😂😂

Destruction tests are meant to be conducted with the people on the outside of the vessel watching on monitors.

Lots of inaccurate information in this video.

Superpb

It's insane to think that the energy in this is five times the low end energy - and so within the range of a detonation of the W54 nuclear warhead (using in SADM demolition charges, or the Davy Crockett manpad.)

11:30 I lost it ...

I think the piece his design team missed, was analyzing the low cycle fatigue limits through a properly modeled finite element simulation. Which would have required product testing to establish conservative material properties, based on the haul manufacturing.

Oof magoof

Maybe they should focus on practicality instead of makong everything into an art project.

They calculated 114 mm hullen thickness but gave it a WHOPPING 13mm extra out of safety consideration

That thing was a carbon fiber casket...

CFRP also _fatigues_ more in than Titanium. So the Titan did fine for about 50 dives, as they ignored all the stress on the hull. Then the last time-- CRUSH.

Thanks 👍. Why don't you make a course on Abaqus simulations and sell on Udemy, people will pay for quality content.

Why can't people leave poor David Attenborough's voice alone. AI voices are utterly cringeworthy turning me off content using them. voice alone.

Mr Rush in Borneo, THE Highlight.

This video starte.d with a plea for money from a well known children's hospital on my phone...I gave to the charity...my info was promptly sold elsewhere...I received over 60 different beggers in the mail several times each..it has taken me months to slow it down and my time and money...I now only donate to one or two and only anonamously...watch out...😢
