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

After its pushed thrue, the hole will have roughly the shape and size of the ball. if u shoot the cannon ball thrue, the hole will be way smaller then the cannonball and can fit thrue. materials behave strange at high speed impacts and they start vibrating. The softer the material, the more it behaves like water and changes its form. also heat will get created + spinning of the projectile when the weapon has a rifled barrel. there are many aspects that are important. watch the video where they shot a piece of plastic with a railgun onto a metal plate. They wanted to test the impact of space debris. this small plastic part made a dent into the metal. If this plastic piece was simply pressed against the metal, it would be destroyed completely without even leaving a mark on the metal. speed is strange and a league of its own. Imagine a comet coming down to earth and the destruction a 100kg comet can make. impossible with just pressing it against the earth crust.

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.

From what I vaguely recall Depleted Uranium is heavier than lead and harder than copper but behaves like copper thermite on impact, basically burning 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.

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.

Newton and penetrator impact depth, has something to do with the density of materials, the theory of bunker buster weapons.

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.

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

This should be called the Mickey Mouse Hydraulic Channel.

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

doesn't DU have a higher hardness of around 50 RHC?

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....

1. Depleted uranium has a property known as adiabatic shearing where it become sharper as it passes through material. 2. Depleted uranium is pyrophoric where it will ignite at high temperatures, (as in those created by the friction of passing through armor). 3. It is way more abundant.

Hello, Where did you get that tungsten carbide shell ? Thank you,

Bro had to bring out the a10 rounds 💀

The mechanism of action for DU is its weight combined with being pyrophoric, i.e. it burns in air. When it hits a target it becomes a molten penetrator which exposes unoxidized uranium to the air and this burns sucking all the oxygen out and killing everyone inside.

@keithpennock

Ай бұрын

Small correction: Pyrophoric means “ it likes to burn.” It’s not the presence of air or oxygen but rather upon kinetic impact it self-sharpens by burning away the outer layers as it penetrates deeper within the metal. There isn’t enough DU in a round or several to “suck oxygen” out of a tank or armored vehicle cab, especially with in rush of air from the breaching hole but rather its main lethality comes from spalling inside the tank, ricochets & secondary detonation of ordinance & fuel.

"Don't replicate this at home" like everyone has a hydraulic press and multiple variations of armor piercing ammo available

D38 is pyrophoric at high velocity impact.

FREAKING AWESOME

couldn't help but notice the .50 BMG was an APCR round

Now press tungsten into uranium on top of carbide disk. 😮

I was not expecting the result with the tungsten. I thought it would shatter.

And why do we use depleted Uranium over tungsten carbide again?

DU when fired at high speed self sharpens as it goes through armor.

Going for Fusion some time? 😜

To question @lambdaprog point (i concur with it) What is the weight ratio from DU to Tungsten? Also, since the west went to DU, I'd like to know the velocity to penetration VARIABLES...Ok i wont find it here, but I want to pose questions

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

Cool to watch but it doesn’t tell us anything, a even a low velocity 22lr would definitely go through 1 mm aluminum and where the gell did he get a DU penetrator?

The reason for those inconclusive results is the lack of kinetic energy. On impact, the part of the target that got hit, becomes part of the projectile.

was that 9mm the swedish ap?

It's official, tungsten carbide's what the Rev-9's made of. :P

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.)

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

7:35 Wow and tip is not even broken! Can you try next time 5cm or AR500 plate and tungsten core???

AP round rely on velocity and the mass of the object to pierce armor. At least on the cast of ballistic weapons. Things like a HEAT round are a bit different as it’s using high explosive and a shaped charge. But weapons like my Russian PTRD-41 used a tungsten cored round to penetrate the armor at high velocity.

DU need the energy of impact to generate the needed heat to really work, don't think pressing it will do the trick?

lol @ all the professors complaining the hydraulic press didn't properly fire the Uranium round. 🤣

The secret to armor piercing is velocity

Everyone seems super upset that tungsten carbide is way harder than depleted uranium for some reason

The core material is only a small part of the equation, velocity is many times more important

Doesn't the A10 GAU 30mm gatling gun shoot 70 rounds per second at 4,000FPS? The cores of the rounds are depleted uranium that naturally burst into flames upon impact/penetration? I'm no expert but the slo-mo press can't compare to the real world scenario of seeing them obliterate tank armor on impact.

I suspect DU acts a little bit like a non newtonian liquid does at velocity.

Tungsten Carbide is much better than DU. But DU is more abundant and cheaper than Tungsten for slight lesser quality

I don't know the Physics behind this. All I know is that I have fired a 40 grain .22 LR copper plated bullet at a 3/8" thick mild steel plate with very little to no damage. I've also fired a 30 grain .22 Magnum copper jacketed at the same plate and made a dent aprox. 1/2 way through the plate with a corresponding bulge on the back side of the plate. The only difference between the 2 rounds other than weight and one being copper plated and the other copper jacketed was speed. The .22 LR was rated on the box at 1070 fps. The .22 Magnum was rated at 2200 fps on the box. Speed does make a difference for sure even with a lighter projectile. I believe that I also fired a .40 grain .22 Magnum and I think it was rated at 1900 fps or so, with similar results to the lighter faster magnum.
