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
@@joemichaels4231 ускорение важно - а ускорение у быстрых подкалиберных самое быстропадающее. Подкалиберные, они быстрее летят (1410 м/с), больше пробивают, но хуже нормализуются и быстрее теряют бронепробитие с расстоянием, чем стандартный снаряд танка - бронебойный
??????? Wtf is unrealistic?? Bullet get smashed by press and break metal? No unrealistic here here...your literally watching bullet get smashed into metal
Testing method is not relevant to how they supposed to work..but what ever…this channel is called “Hydraulic Press” so it super relevant to their content context 😂😂😂
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.
no bro burning effect mostly important when weight lose lot of so not uranium highly weight the good point only burning like a HEAT cumulative effect the good thing 250BHN vs 600+ BHN good armor( like a T-80 what made 3x50mm 600BHN armor) will be break any uranium APFSDS M829Axx ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Bfo494lp_dE.html
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.
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.
@@Canthus13This is tungsten carbide, not tungsten. Very hard and very brittle as well. Unless he has it wrong - I think there are both tungsten and tungsten carbide cores.
@@OnTheRiver66 I'm not sure, honestly. I don't know if both are used. I do know that tank rounds only use DU because tungsten doesn't have an incendiary effect like DU, and the penetrator gets rounded off as it penetrates, unlike DU which gets sharpened as it penetrates deeper, and then fireballs inside the tank.
@@Sukhoi47Berkut1 no with speed it defenitely behaves differently. Try to push a cannonball thrue thick wood planks. 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.
A lot are saying it’s not a relevant test, I’d like to point out it appears to be a material strength test not a direct comparison to how the projectile works once fired demo ranch does this part. But for what is being done in the particular video has relevance in compression resistance of the tested materials.
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.
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.
.223 FMJ round will pierce 1/2" mild steel at 50yds, 1/4" at 100yds all day (I was using some old steel I had lying around as targets in the woods...I expected the targets to hold up better than they did). As said below, it is the result of the velocity that makes it penetrate. Cool to watch though, I thought depleted uranium was harder than that, and expected both to penetrate without deforming nearly as much, and did not know tungsten carbide was that much stronger than depleted uranium. Thanks for the video !
@wildmanjeff42 try purchasing a thin rod made of pure chromium metal(diameter 1/8" for .223,1/4" for anything like .308,.303,30-06,7,62×39 or 7,62×54mm,8mm mauser,etc,5/16" for anything 9mm to 11mm and 7/16" for .50BMG)-cut it into pieces and sharpen each of them using diamond disk on an angle grinder while they are spinning in a drill press or anything that will spin it-even a cordless drill will do albeit it's much better to use drill press or lathe..And yes,the only thing that can be used to effectively machine chromium metal is diamond:conundrum,garnet,ruby and other abrasives will take forever because they have the same hardness as chromium while tungsten carbide is inferior to it! And then try using them as penetrators:I guarantee you will be amazed at what they can do:I definitely was fascinated by it's performance!
You cannot approximate what an armour piercing round will penetrate with a slow moving press as opposed to being shot out of a gun, the physics is all wrong.
Not if you're looking for deformation patterns, expansion, and general material displacement characteristics Not close to the same as firing a round, but definitely not without merit
And that, the objective is not to simulate shots, the objective is to compare projectiles and it is practically valid because they are in the same conditions
Love all the people talking about how the rounds would perform under normal conditions, but the channel never stated that this is how they'd perform normally. It's just a hydraulic press channel yall, calm down and enjoy it
Reminds me of my younger days making hole punches for punch and shears in the metal working shop, we could punch a 20mm hole with a 20mm punch, just got to get the right steel to make it out of and then heat treat it just right
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.
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. The description that comes to mind is like a pressure washer full of molten copper. As far as the DUP, the friction powders the metal and ignites it. It's a dense, high speed blob, the self-sharpening is from the crystalline structure.
DU is still somewhat radioactive, so take care around it. Also, it's used for AP rounds because of its density, not its hardness. It's significantly more dense than lead. Tungsten is very slightly more dense yet, but is also very hard.
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.
Density: DU is much denser than steel, giving it greater inertia and allowing it to penetrate deeper into a target. Velocity: DU projectiles are typically fired at very high speeds, which further increases their penetration capability. Shape: DU projectiles are often designed with streamlined shapes that allow them to pierce armor more effectively. In conclusion, while DU is less hard than steel, its combination of high density, high velocity, and optimized shape makes it an effective material for armor-piercing munitions.
a good answer is u need a certain amount of strengh in the material, but wath u need more is speed and density ... so go for titanium or depleeted uranium ^^
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.
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.
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.
В отличие от вольфрама, уран на высоких скоростях получает возможность прожигать металл при контакте со сталью, и к тому же сердечник с обедненным ураном самозатачивается.
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.)
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.
@@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.
@@dsan2910 uh... nothing I said was incorrect. It is pretty malleable. I never compared that to lead. Only its density. Read a bit better before commenting.
Y there so many mfs yapping about how it's not realistic like we don't already know that. It's literally a hydraulic press channel not a ballistics one 🤦
It proves clearly the difference between a static test vs dynamic. In reality even a 22lr bullets would go through the aluminum sheet and wood. (About 10 centimeters of wood point blank)
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.
What some people dont really know is, that DU isnt exceptionally Hard, but it is cheap (its a byproduct) and its very dense and it self sharpenes upon penetration. (That doesnt make it the best option tho, as its still a waste product, and there are more modern Tungsten alloys, that are simply far better, also self sharpening and arent an environmental harzart.)
Do NOT breath in the depleted sabots dust. Do not hold in bare hands, DO NOT lick! DO NOT GRIND AND INHALE!!! No lines of DepU. We machined Depu Enclosed with dry machining cycle. A special hazzmat truck would handle all the swarf for recycleing / disposal.
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.
It’s the speed of the bullet or projectile that gives it a piercing ability not a slow hydraulic press , this is not a fair show of the ability of the projectile what can truly do.
DU (depleted Uranium) isn't made for this kind of application that's why it performed very poorly on a hydraulic press. It's main selling point is it's density. It's heavier than any metal and when it comes to kinetic munitions, weight and velocity is everything.
Pure tungsten is a little denser than uranium. Tungsten Carbide is about 20% less dense. 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.
Second PS Copper hardens at ultra hard velocity and temps before its matter has a chance to change. It gives a punch thru efferct superior to steel. The best are Gold, Copper, Silver as I recall. Physics get funny at very high speeds and short moments. I didnt believe it till i watched ballistic high speed vids ! Crazy COPPER is WAY harder then steel for a MOMENT in time...just long enough it seems...Steel goes all liquid before so the copper wins!
Depleted Uranium is about 35% denser than Tungsten Carbide ... that gives it much more lethality against armor than TC. I have personally seen the damage from a DU shell on a tank through the thickest part of the armor and the hole it made through it was as if that armor was made out of butter and the softer DU sort of melts along the metal it is pushing through and splatters all through the inside of the tank. Nothing would survive inside that tank. I do think that DU shells should be illegal as I believe the dust it creates is extremely harmful to humans and the environment, even though it is supposed "depleted". |t should be treated the same as chemical weapons or nuclear weapons.
The tungsten outperforming the DU isn't surprising in this scenario, given that they're meant to be moving muuuuuuuch faster. If memory serves, the DU rounds are self-sharpening when theyre moving at the speed of mach jesus 😂
Tungsten also outperforms DU in higher velocities. DU is used because it gets the job done on present generation tanks. If higher exit velocities become the norm, tungsten will be used.
