No. Certain alloys and heat treatments of steel have terrible fatigue life. Same with Aluminum. The issue is the crystal structures and inclusions (what is alloyed with the Fe or Al) that create the material properties. The geometry of the crystals (size, dimensions, orientation, and how they interconnect to each other) is what gives a metal it's mechanical properties. The different inclusions (alloy material) that is added changes how the crystals can move relative to each other or the chemical composition of the crystals and the chemical bonds made by those crystals. It is possible to design a aluminum structure for flexural fatigue life. But there are far better alloys of steel for that task for given price point. Inherently the problem is just poor engineering and metallurgy. The guys building it did what they were told. The guys designing it were either mislead as to it's use case or were incompetent. My gut says incompetent.

I feel that navies in general should use Toyota type construction methods and materials: reliable time tested hull materials and propulsion. Built one of a new kind and test it for at least two years before committing to a large order. It might sound impractical compared with present procurement doctrine (to spread out the cost of R&D on a large order) but it seems the right alternative based on recent experiences. The Zumwalt makes this point more evident. It's just a point of view of the large costs involved in shipbuilding and commissioning.

Aluminum will always crack with repeated stress. The biggest snafu is designing the ships in a way not anticipating having to do frequent fatigue repairs and making such repairs difficult to do. Aluminum works on aircraft because you can reasonable predict the load patterns and cycles and know when you need to replace things or retire the aircraft. Ships have the randomness of the waves to deal with which adds in so many variables that it's impossible to predict. Magnesium and zinc both are metals that don't fatigue but react rather quickly with salt water in galvanic corrosion and titanium is another HCP material which doesn't fatigue but is much more expensive and difficult to weld and work with. This leaves the good old Body Centric Cubed crystalline materials of iron, moly, chromium, vanadium that interestingly enough all alloy together into something we call steel very nicely which have a defined endurance limit. There were good reasons for the Independence design to be built from all aluminum. From fuel savings, to being non-magnetic. But thrashing through the ocean at 40 knots or more it should have been known they would suffer from constant fatigue cracks considering how long Austal has been using aluminum and the long history of it.

I have an idea for multipurpose amphibious assault ships with modular runways. Two ships joined together would have a length of 475 meters and could be as resistant to waves as a skyscraper. Shock absorbers can be used, which make it flexible and are used in the columns of skyscrapers. Thus, aircraft carrier costs are reduced by 10 times.

These ships are equivalent to Russia's aircraft carrier in some points: 1. It costs a lot of money to operate but they are still using it. 2. Needs careful sailing because things might break apart even with the slightest unfavorable conditions.

Thankfully (or not, depending on your point of view) the US has the financial depth to take a financial hit like this without missing a beat. I think the fundamental problem is that we all KNOW that fact. In the knowing of it we are more likely to make more risky plans and less likely to call a halt to an underperforming program of design, development, or procurement order. PARTICULARLY when it's a massively expensive item that relies on economies of scale to reduce overall cost per unit. Something goes wrong, costs skyrocket, the number of units to be acquired slashed, and around and around we go, whichever party is in power changes not that status quo! 🤪👈 That said, Russia only built two of their "aircraft cruisers". They built them without having built any of the infrastructure neccessary to support them, without the planes to fly from them, and without the necessary battlegroup attendant fleet or any tactical doctrine to even THEORETICALLY use them effectively in any way whatsoever. The COST was...... insane too. The fraction of the entire Russian military budget spent on just those ships was utterly, absurdly mind numbing. Granted, they did what Russia always does to compensate for its military and/or political inadequacies - they stuffed it with a comic lying obscene number of guns, missiles, bluster, and lies. It didn't work any better then than it has for Putin now. Also different is the importance of the ships to the military and nation. Our LCS ships were never going to be flag ships of the US Navy. Our national pride wasn't at stake. The exact opposite was the case for the thwn Soviets, now the Russian federation.

@ravenouself4181

The two cases are not truly comparable. Let me explain. There is nothing wrong with the Kuznetsov's design or structure - the problem is the supportive infrastructure and the consequences of not having it. It's systems, such as the engines, generators and water desalination plants have been abused due to the lack of said supportive infrastructure. And to finish off about the Kuznetsov, India and China both operate Kuznetsov-class ships and they have no major problems, why? Because they had infrastructure capable of servicing such large ships beforehand. The USA has the opposite problem. It's supportive infrastructure is second to none, but it's ships have design and structural flaws. Furthermore, the USA has had structural problems with it's ships for decades now and with multiple classes of ships. Finally, we are comparing a ship from the 1980's to modern ships made from the 2010's onwards. What I am trying to say is - the USA needs to abandon these dysfunctional failures of ships and design and build new ones that actually work.

Of course these things need to be cheap, which means they have to be relatively small. Of course that limits it’s range, so it needs to be launched from some sort of mothership or dropped from aircraft.

This is stated in the video. And it's not just "the type of aluminum mix they used" it's any aluminum period. There is no form of aluminum that is okay to use under constant stress, as it doesn't rebound from that stress. It rips on a microscopic level no matter how little stress is applied to it. And until reforged, those cracks never go away. Try bending a can until its dented then work out that dent, it will still be very weak in the creases no matter how perfectly reshaped it looks.

I think they were heavily lobbied by the aluminum manufacturers. When the damage was done the Navy demanded the production of the LCS to stop in addition to every other ship using it as a superstructure and they tried to change them to steel or something. The aluminum producers hated that and said that if they did, they will sue the Navy. The producers argued that it was not the aluminum that caused it, but tests seems to say otherwise.

The other issue was what these LCS models were going to be used for... mine hunting. Low-magnetic (degaussed) steel is EXPENSIVE and HEAVY. The ship wouldn't have the speed the Navy required nor immunity to older mines IF they had used steel. The irony I see is that neither mine hunting nor littoral operations require a high degree of speed, so that speed requirement was a waste of resources for a mine hunter.

The report mentions galvanic corrosion at one point. This occurs when a potential difference typically in the tens of millivolts is set up across two dissimilar metals (assume aluminium and zinc on galvanised steel) separated by an electrolyte such as sea brine. This has been described as the aluminium "fizzing away" in cruise ships with steel hulls an aluminium superstructure. I can only assume that part of the problem here is the use of dissimilar metals in sea water not simply the engineering properties of welded aluminium. The tell tale signs of galvanic corrosion are visible corrosion a p.d. (voltage across the metals) and the evolution of hydrogen gas !

This is the best KZread channel in history

Interesting fact about steel hulled ships with aluminum superstructures. They use implosion welding to join the steel and aluminum. The metal comes in strips a few inches wide by two or so thick that are aluminum on one side, steel on the other. Theres a cool pattern in the middle where the sheets of metal were bonded together using explosives. Everything from the main deck up is sitting on those strips. Thats how you make a steel hulled ship with an aluminum superstructure. I worked for a few shipyards in my late teens early twenties. I picked up the metal from a supplier and was told absolutely dont let anything happen to those strips, they're expensive. Which immediately made me wonder if I was allowed to let something happen to all the other stuff I picked up. Turns out no, no i was supposed to protect that too. Stupid job.😁

You'd think that with all the known issues with cracking in aluminum superstructures that it should have been obvious that building an entire class of ships out of this same material should never have been considered much less implemented. This should be even more of a no-no given that in the littoral waters where wave action would be even more pronounced and the possibility of encountering small boats turned ad-hoc military craft that if not neutralized quickly could inflict a fair bit of damage in short order. Since the USN has previous experience in how fast and complete aluminum can weaken and collapse, as was seen aboard the USS Belknap, it makes no sense to make an entire ship out of this same material. The loss of some speed would be a fair tradeoff to make to have a hull made out of steel.

so from what I'm seeing and I'm going to say now I'm no physics expert but judging by the fact if they come across rough water bow on they can stress mych more likely, my guess is this isn't due to the aluminum hull but the actual tri hull structure itself. the complex design of the hull literally has a massive problem where a giant bow is connected to the side hulls with a convex plate armor. every time this thing hits waves that push up on the bow you have a few seconds where the weight of the ship is hitting a wave at speeds where the waves are hitting super hard and the bow is taking that stress and carrying it to those convex plates where stress fracturing is likely as the bow wants to go up and follow the waves for a few seconds and the convex plates are going nope you stay still. this repeated stressing is whats likely causing the stress cracks to appear. if this was scaled down in the front by 30 feet it might have reduced the stresses its recieving but only minorly. if you look at smaller boats with tri hull designs they don't have massive bow structures that are more than 30% of the length of the ship. likely earlier boat designers knew if you did there'd be heavy stressing of the connection between the central hull and side hulls so they never upscaled them to this size.

that pun in the stark CRACKED me up xD ++

One notable mention: The T2 class, basically the same thing as Liberty ships and Victory ships, but tankers, had a track record of breaking in half, why? Cuz, well, the welding and the speed at which the ship was built, didn't go over well. S.S Pendleton, and S.S Fort Mercer, sank off cape cod in 1952, coincidentally, both were near each other when they sank-

I got a peek at the structure ,my opinion it does lack some organic features like honeycomb .

who actually designed the LCS? I feel like they didn't plan for them to be used except in perfect non combat conditions

That shot of Naval war systems ship bridge infrastructure is right on the side of the road, Route 95 south I believe, built on land. I used to drive by it once in a while when traveling. NJ or Delaware, I can't remember.

The humour leading up to the broken fork, it’s not what I thought.

ALUMINIUM will always fatigue over time, unlike titanium or steel which require a given stress load. Aluminum is lite and stiff, but comes with a cost. Same thing happened to my aluminum bike frame, but not to my titanium or carbon fiber bike frames.

@simonm1447

2 жыл бұрын

90 % of the bike frames sold in western countries are aluminum bike frames. They can crack, but only few does. My aluminum E bike frame has run now for 22k km, it's used to transport heavy stuff sometimes but it's still fine, in this case they didn't make the material extra thin to squeeze out the last gram for weight saving. Carbon fiber has a completely different fatigue characteristic, it can delaminate over time, and it don't bend - it stays flexible to the point where it snaps completely. Contrary to metal however carbon fiber is sensitive when it comes to side impacts, since it's a fiber material with the most strength in fiber direction. Concorde had a carbon fiber rudder, there was one case where a Concorde lost half of its rudder because of undiscovered delamination.

I always wanted to be a failure investigator, which consequently led me into taking an interest in metallurgy and materials engineering. Shit is awesome when it breaks, because people like me can go full autistic into root cause analysis and mitigations.

How many of those analysis boil down to shouting at the braindead engineer who thought using a material without an endurance limit on an area with cyclic loading was a good idea? Because I hope not to become that kind of engineer.

From what I know and have heard earlier weld cracking had a lot to-do with HYDROGEN EMBRITTALMENT, 6018, 7018, 8018 etc. steel welding electrodes also called "Lo Hi electrodes" short for "Low Hydrogen" that were NOT heated in a special "rod oven", at hi temperature s for a specific length of time and use within a short time, would absorbe moisture. That translated into "weld bead cracking",

With regards to the liberty ships, in order to manufacture them in a matter of weeks, all the metals panels of the ships hull had to be welded instead of riveted. So what had was, once a crack started to form from example shell impact, the hull would start to crack and keep on cracking until the ship was cracked in two. If a shell had damaged a panel on a riveted ship, only the panels around the impact would get cracked/destroyed, but the crack would propagate through the rivets through the rest of the ship

I bet those ship class comes with some of the auto dealerships 5 years limited warranty. So wasteful, why keep making those if they not gonna last?

Those ship looks cool though. A ship of this class I see in real life. And this is the only American ship I see in real life.

Kinetic energy increases as the square of the velocity. Ship flex is measurable so you can stress the ship in various ways or test models, then measure the flex. This flex can be calibrated against the design software. The properties of materials used should be well known. It appears that Austal has a crummy engineering department, or management is interfering with them, and the Navy is incompetent to oversee the process.
