HYDRAULIC PRESS VS ARMORS PIERCING CORES

[@lambdaprog]

The main operating principle behind projectiles is high matter density at high velocity, not high strength at low velocity.

[@tenhayz1889]

I dont think that makes any difference, it is just force being applied to the projectile. However, the hydraulic press increases weight progressively while a projectile hits its target at full speed. Id say the force being applied slowly by the press makes it harder for the projectile to penetrate

Thank you. He’s not trying to make a projectile video

[@SingularityAdvent]

The depleted penetrator, is self sharpening during high kinetic impact. You can see that tiny side walk in the vety beginig. At high kinetic impact, the penetrator, doesn't have "time to deform", it just errods itself and self sharpen. And will have a side walk while still perpendicular on the impact surface. Tungsten is great as long as it remains perpendicular. If it deviates even a little it would most likely bounce.

It's not relevant because he's testing DU - not staballoy. DU is not used in armor defeating ammunition. Instead, it's staballoy - an alloy of DU and molybdenum. Also the physics being used are incorrect. The impact forces when kinetic energy ammunition penetrates armor cannot be modeled using the physocs for solid materials. Under those forces and pressures that armor and the penetration both act as if they are liquids.

Depleted Uranium pyrophorically sharpens upon impact at high velocity, that is why it is used in depleted uranium armor piercing rounds and armor piercing fin stabilized discarding sabot rounds (APFSDS), your test disregards this kinetic energy effect and it cannot simply be substituted by a weighted pressure test. There’s a reason armor is tested by live-firing range tests.

Pressure applied through rotation and velocity reacts much differently than slowly applied. Agreed. Even weaker materials will create massive devastation at velocity and yet near nothing when pressure is applied with out a shock load.

[@gregmarsters2434]

As explained to me by a community college chemistry professor (shrug) Proper forging of DU is needed so the metal grain structure supports a graphite-like shedding of material that both lubricates and prevents deformation of the main body so that its cross section remains minimal as it pushes aside-through tank armor. The pyrophoric behavior is a secondary stage where the hot uranium high surface area "dust" behaves much like a fuel-air bomb mixture as it mixes with oxygen.

[@iamhe999]

depleted Uranium weighs more and therefore hits with more kinetic energy...

[@anomamos9095]

From what I vaguely recall Depleted Uranium is heavier than lead and harder than copper but behaves like copper thermite on impact, basically burning on its way through the armour and most especially burning after it passes through the armour causing maximum harm to anything behind the armour. Note When I said burning its way through I was being slightly poetic not describing the mode of penetration. The penetration mode is almost entirely kinetic, but what occurs is the uranium spalls as it penetrates becoming little balls of molten burning metal that destroy the inside of the target.

[@kennybachman35]

The shape charge breaches the armor and the molten copper follows it through the hole. That’s why AT armor is just a mesh/fence around the heavy armor. To set off the shape charge before it hits the hull.

First of all the tip is 'self' sharpening' so and pieces break off the tip remains needle sharp. (So sharp that service (combat) kinetic energy ammunition comes with foam covers so than crews don't cut or puncture themselves while handling it. The increased density of staballoy means that a smaller diameter penetrator can be used - which improves armor penetration capability. However that is a happy side benefit. The big reason is because staballoy has 'after armor effects.' When the projectile exits the back of the armor it becomes a white-hot storm of burning shotgun pellets. These penetrate the spall liners protecting the ammunition and destroy the armored vehicle by detonating the on-board ammunition.

In modern APFSDS ammunition (Armour-piercing fin-stabilized discarding sabot) depleted uranium is used in the USA, in other armies often tungsten heavy metal alloys. Depleted uranium has a density of 19.1g/cm^3, the tungsten heavy metal alloys have between 16.85 g/cm³ and 19.7 g/cm³, depending on the alloy used. Tungsten is significantly harder, but uranium has the advantage that it is self-sharpening at these high speeds (provided it has been manufactured correctly). This self-sharpening property and the ignition of the uranium when it ignites internally after penetration are two properties that greatly improve the effect in the target and the penetration properties. This is why the Leopard A6, most versions of the A7 and the soon to be released A8 have a longer version of the original gun that can withstand even higher pressures (They use tungsten), This results in a higher muzzle velocity, which means better ballistic characteristics and more energy on target over longer distances. This should compensate for the minor disadvantages of the tungsten ammunition. Why is this effort being made? The M1 Abrams fires uranium and gets along well with the L/44 cannon (the old Leopard also has this cannon, the new ones have L/55). The reason is that studies have shown that the incidence of cancer in the population has increased after the use of this ammunition. Many countries don't want that. But the bottom line is that I think the decision to use uranium ammunition is mostly a financial one. Uranium is super cheap, tungsten and especially these alloys are expensive as hell in comparison.

How interesting that the hydraulic press demonstration shows such a performance difference with no Velocity.

Newton and penetrator impact depth, has something to do with the density of materials, the theory of bunker buster weapons. I had expected the uranium to burst into flames, but it dodnt get pushed hard enough, the reason uranium is used is it melts into a hot penetrator, like a shaped charge explosive, better than tungsten. It also catches fire. The problen is the urinium didnt get hot enough.

[@UninstallingWindows]

Shaped charges don't actually melt into a penetrator. They remain solid. Its not really the temperature that causes damage, its the kinetic energy(speed and mass). A small pebble will punch a hole into a tank armor if it moves at an orbital speed. The faster an object moves, the less time the target material has to dissipate energy. If an object cant dissipate incoming energy, it will disintegrate.

@UninstallingWindows Anything rapidly compressed is more like a liquid jet. If you see IED hits, it looks like someone poured copper on the inside.

It's a dense, high speed blob, the self-sharpening is from the crystalline structure.

For anyone wondering why they use uranium, it’s typically spent uranium from reactors that’s not very radioactive any more, and it’s used because it’s very dense, even more so than tungsten, which allows it to punch through the steel at high velocities, the same way lead projectiles can, plus at those velocities, once the tungsten starts to deform, despite being harder, it will tend to mushroom and create a larger point, where the uranium will simply abrade away, maintaining a sharper point that allows it to penetrate farther as it uses less energy.

I am not surprised the tungsten went thru like a knife thru butter its insanely strong. The depleted uranium I didn't expect to crush like it did. It's pretty impressive to see how much they change without high speed as a factor.

[@colincampbell767]

DU is not used in kinetic energy ammunition. Military armor defeating kinetic energy ammunition uses an allow of uranium and molybdenum called 'staballoy.'

[@O8WRx]

It's a good example of how velocity can effect things. It would be cool to show students this, and then what happens at shot velocity in slow motion on the same set of materials as a target.

[@WilliamTaylor-h4r]

The uranium has less wind resistance per velocity, like if you throw a piece of styrofoam, so its pointed at the target, the plane is a giant foamy, but its all gasoline, you just run out of ammo when you miss. As long as its rotating, it's impossible to miss because the foamy can track perfectly at 50ft wingspan.

[@willj1598]

Other than the inherent joy of smashing things I'm not sure there is a point but I watched it.

[@michaelray5595]

The thing about deleted uranium rounds is that they get extremely hard at high velocity/high temp friction and slag thru armor. The intense heat causes the armament inside the target blow.

No way that was depleted uranium.

Yes, it actually is. It is pretty malleable. It is also heavier than lead. That's why it is so effective.

[@dsan2910]

@@Andy152R incorrect. Depleted uranium (DU) is not highly malleable in its pure form. It is a dense and hard metal, similar to lead but harder and with a higher melting point. However, it is less malleable than metals like gold, copper, or aluminum.

I use carbide cutters for work as a CNC machinist. They cut through steel like a router blade through wood. Crazy. Tungsten carbide alloy is even harder than that. My wedding ring is made of tungsten carbide.

[@NuhuhTM]

Note: the “Depleted uranium” penetrator is tungsten. It exhibits tungsten’s mushrooming effect, and depleted uranium, especially on the civilian market, would not typically have their exterior cleared of any oxidized impurities due to its pyrophoric nature.

[@mxbxx]

Of course, wolfram is better, but it is much more expensive than depleted uranium, which is a by-product, i.e. waste.

[@Sukhoi47Berkut1]

Could you imagine somebody making large capacity supersonic rounds out of tungsten probably go through buildings like it's made out of butter.

[@quietanonymous]

I think the navys rail gun uses a tungsten projectile

[@optymus333]

Awkward

[@jasontrevis7142]

The projectile needs to be hard enough to penetrate its intended target but soft enough to expand after penetration to cause the maximum amount of damage.

[@RacesForTheChannel]

They do make those. They are called slap rounds.

[@johndoe-jg7he]

Like the KE-T APFSDS round we routinely use? Everyone and their sister is making tungsten rounds and all of them are quite supersonic. DU is better though.

[@Flies2FLL]

Depleted Uranium is used as airplane control surface counterweights. It is very heavy, that is why it is used, while tungsten carbide is very hard and will penetrate nearly anything. A GAU-8 shell works because the velocity is such that the uranium liquifies on impact and sprays inside the interior of the tank, destroying everything and killing everyone on board.

[@Caliber50bmg]

“Armor piercing rounds” ……btw. Friendly criticism 😊

[@_RsX_]

At high velocity probably, but with the press they are pearing out 🍐😁

[@eidolonis]

They are. The entire basis for armor piercing ammunition is velocity. Think of body armor tests, a rifle succeeds at penetrating far more than handguns because they have much higher velocities (gross simplification obviously)

[@deltahouse-o3b]

Esta mal esa prueba !!! la penetración del "Uranio Empobrecido" es por densidad no por dureza, sobre todo a las altas temperaturas que se generan por la fricción del impacto, el uranio conserva la cohesión atómica y al ser mucho mas denso penetra los blindajes...

[@richardlynch5745]

waste of time 3:04

[@Leptospirosi]

The point of a projectile is to transfer the full kinetic energy as fast as possible to the target in the smallest area possible. Hardened steels is very difficult to penetrate, but there is a work around, which is heating it up to the point that it's no more hardened and becomes fully plastic. Velocity is key here, or how fast the energy is transferred to the point of impact: the faster the transfer, the less time heat has to spread up across the armour plate volume. At high velocity, an AP projectile literally melts a small area of impact, to the point that an AT projectile destroys the tank interior thought a shower of melted metal, both the armour and the projectile which overheat the area and explodes through heatwave expansion, hydraulic fluid ignition and and stored shells explosion. This is why most of the killed tanks have a intact hull with a shell sized hole, but the interior is completely wrecked. Composite armour aims to contrast heat build up on a small volume, through spreading into different layers that deplete the projectile energy into different materials and spaced areas, so that the heat build up becomes inefficient and the penetration reverts to pure ballistics and mechanical transfer, which is what we see in the hydraulic press test.

[@VeryDeathlyShiny]

In Halo, the orbital defence cannons around Earth, Reach and other major colonies, are a magnetic accelerator cannon powered by ground-based fusion plants (they beam the power up via targeted microwave radiation) that fires a 6000 ton tungsten slug at .06c - aka 6% lightspeed. They are beyond devastating.

[@raffs_adv]

Wow, your rig is a beast.

[@bobbyduke777]

Yes the weight of the depleted uranium is what sends it through heavy armor, not the hardness. It is heavier, then lead.

[@SMlFFY85]

This is a channel that squashes things, guys, relax.

[@dariousvex]

Damn dude. That tungsten carbide did not even scratch.

[@jeffthacker569]

Did the tungsten actually cause some "melting" as it penetrated? It appeared there was some wetting around it

[@KindOZiggy_TV]

This is a wonderful example of how you drive a bullet in manual.

[@The_Cynic]

That tungsten got suspiciously polished

[@aiden9598]

I understand this is not how the uranium core is suppose to be used but when it’s being shot it acts as self sharpening and flasks of as it penetrates keeping it sharp

[@cdrkennon]

DU is used not for its hardness but the thermodynamic effects. On impact it is converted to plasma, which burns a small hole through the target. As the plasma gas jets into the interior the extreme heat of the plasma-temperature gas causes it to combine with oxygen with an explosive effect, the shockwave rise time so intense it is in effect a fuel air explosive. The DU burns through as layers convert to plasma; the resultant explosion destroys the target.

[@jgedutis]

Did you get the uranium dart off Amazon?

[@artasulla2801]

Try with plate tungsten, maybe another different result. You can try?

[@benborah1264]

It all comes down to the velocity of the projectile- look at tanks from ww2- longer barrels normally resulted in much harder hitting ordinance than shorter barrels did (panzer D vs F2 for instance.)

[@MichaelMckinnon-q6e]

It's just the projectile, no propellant involved, so it's perfectly safe unless you're dealing with the depleted uranium which is still radioactive and could most likely be recycled and enriched again and reused for the purpose that depleted it

[@Flxwless_Official]

This shows why we should use tungsten for more things including racing because I feel like if we start using billet tungsten blocks and heads then top fuel dragster engines would last longer than 1 run which makes drag racing so much more cost efficient

[@shotgunmatt1]

Tungsten Carbide V Depleted Uranium ~ That is intensely interesting to watch, but it's also highly misleading. DU is heavy ~ it's heavier than lead. When it arrives at two or three thousand foot / sec, it punches through things like hardened armour steel like no other substance. The way it deformed? Like butter? It does that at high speed too, but that means it has an outer layer, and an inner layer, and the two slide over each other. It becomes like a viscous liquid. The slower outer layer acts like a lubricant for the faster inner layer. It forms shells, like a Russian doll ~ like an onion, and the inner one just keeps on going. It is a nasty toxic metal (I note you are careful to wear gloves) but nothing yet discovered punches through armour as well as depleted uranium. Doing it all at the speed of a hydraulic press ~ that's interesting, but that's not what happens when an armour piercing round hits armour plate at well over the speed of sound. ~~~~~~ Try this ~ make a 'projectile' like the ones here, out of copper. On a lathe. Now try to press that through even aluminium. It won't work well at all. Now watch any of the many clips here on youtube showing a shaped charge. Now make a cone, one mm thick of copper, and put a layer of explosive on it, say 5mm thick, and stand it off a one inch thick steel plate, spaced upwards maybe 4 ~ 6 inches. That liquid slug of copper will punch a bullet or pencil size hole clean through an inch of steel. You can easily do the experiment, or you can watch it being done on youtube, but you can't replicate it at hydraulic press speeds with those materials because the physics are just different at normal speed. It doesn't work at normal speed. But once you turn up the speed and the pressure by a few thousand foot / sec ~ you would not believe how 'sharp' liquid copper is.

[@Knight-Artorias]

Good on you for using gloves when handling these cores. Always gotta be safe, no matter how unseemly the possible consequences.

[@colincampbell767]

DU is safe to handle with your bare hands. In fact, is primary hazard in a workplace is as a combustible solid. All you have to do is follow standard industrial hygiene practices (such as wash your hands before eating or smoking). And yes, I fail to see the reasoning of somebody washing their hands before they deliberately inhale carcinogens and rat poison.

[@mehdighafoori8183]

The difference between tungsten and uranium is that tungsten is brittle upon impact, but uranium ignites at high speed and acts like a cutting torch, ripping through armor.

[@DarkPrject]

The carbide has a nice surface finish after passing through the plate.

[@deanneuburger3869]

Fascinating! Thank you! I thought the carbide would explode!

[@DrewBolin-sk6rw]

The reason the cores did not penetrate is because they were not spinning extremely fast, nor were they hot from being fired from a barrel, the depleted uranium would have probably penetrated the 1/2 inch plate

Consider the tungsten carbide being so hard 90 would most likely shatter under high velocities. Didn't the older armor piercing round have a hardened tungsten steel carbide insert in the jacketed round. Later found it couldn't penetrate newer armor OR the MIC just needed a way to use the depleted uranium from our nuclear reactors....my friend says he was poisoned by depleted uranium rounds from mid east wars...nasty stuff...floating in the air after battles....

[@eidolonis]

Feel bad for your friend, from what I know it's usually as a result of massive burn pits during the gulf wars / that era. They'd pile a bunch of stuff that needed to be gotten rid of, including depleted uranium ammunition, and ammunition to begin with in general, and burn it using jet fuel as an accelerant in some cases.
