Ultra Porcelain Armor | Armor Penetration Simulation 

The armor is stored in the balls

I'm a simple person, but I always love watching the fins on an APFSDS-T round leaving a cartoonish indent where it hit.

That's fairly effective.

That’s an incredible hardness(I’m guessing) to deform a penetrator like that.

An interesting thing to notice is that because the projectile is so long, it gives time for the balls to spin and feed more corundum into the path, pushing different parts of the arrow out of the main line, dispersing the damage. This can only be achieved with round shapes like spheres, and this kind of armor is even more effective against thinner and more fragile shaped charge jets, according to Soviet sources.

Rather different question, but is it possible to simulate a small (or big) meteorite impact on the ground with this system, i assume so? would be cool to see what it would do against a bunker maybe 20-50 meters underground

Gotta hand it to the Soviets, their ideas for composite armor were quite interesting. This is probably the weirdest of the bunch though.

Quite incredible for such turret filler and protection. Honestly when a sim surprise me with a different result is always appreciate, nice one!

Would REALLY love to see how it does against HEAT.

One of the only sims I’ve seen stop APFSDS that wasn’t just a test of different materials and was actual armor

That works alot better than i expected

Ohhhh I made a proposal on this armor in an old video, thanks for simulating that ^^

great work! thanks

Damn, design from the 60's performing very well against modern projectiles, without kontakt-1/nozh ERA!

Was trying to think when these two would have faced each other on the battlefield as they are both older USSR MBTs, and realized has probably come up in the past year in the current Ukraine invasion (and to an extent the various middle eastern civil wars of the past 20 years)

Wow! So efective!

I've often wondered how a loose section of sloped armour plate that moved away from the LRP projectile as it penetrated would affect the cohesiveness of the projectile, would it not act like shears and cause the brittle body of the LRP to fracture or would the damn thing be through before it had time to react?

Interesting design

Wow interesting how HEAT would behave (and processor too)

Very impressive work! Would you share any details as to which numerical platform, material models, mesh vs. meshfree methods, etc. you are using for this outstanding work?!

After looking up the ballistic that round has est 560mm of pen RHA. It would have penetrated comparatively easily. It stopping ~100mm short because of the porcelain is pretty cool

I really thought this one would 💥

Front plate opens up like “yes apfsds come in, there is no composite armor here”

I have a question regarding the material ‘Ultra Porcelain’. I’ve done a few quick google searches in the past trying to figure out just what ultra porcelain actually is. How does it differ from regular porcelain? Higher hardness? How do you make ultra porcelain?

Would love to see a merkava 4 video at some point in the turret and engine with various types of rounds.

They were testing a early version of this to use in the Obj. 279 hull.

Could you do a test with different profile/shape APFSDS? I'm curious to see what a teardrop shaped APFSDS would do, I.E. the front end being significantly wider than the back end. That and various different profiles.

Well, strong balls rules

Interesting cordumn balls hold pretty well With better positioning they could be constantly in the way of rod at an angle

What settings did you use for the dynamic mesh in Ansys? What Ansys software did you use?

Maybe test boron nitride balls and Al2O3 ceramic balls? Maybe put them into abrams front between it's standard plates

Bro took i have a steel balls to a whole another level

Sorry but "Ultra Porecelain" armor sounds like something from a "magical girl" anime.

That tank crews really have a balls to get hit with apfsds

Very interesting, i always knew of the ceramic balls within the t-72b turret but what i wondered was how they interacted with the penetrators, the efficacy of the cerramic spheres in regards to deforming the penetrator was very drastic in comparison to anything i've seen on your channel before! Thanks for another great vid! May i suggest sometime in the future when you feel you have the time and interest, to simulate the effect of round impacts on barrels? From different angles such as 0 degrees frontal, glazing impacts, 90 degrees from the side etc, seeing how the barrel would deform and warp from a glazing impact would be particularly interesting i think. Perhaps another interesting case could be a round impacting and going down a barrel ultimately impacting the breech, a barrel of which is sub caliber to the round iself, seeing how the round expands the barrel etc. Any round or barrel of your picking really, but i would suggest picking older ap solid shot or apcbc (or perhaps HE) so as to have more blunt impact for total deformation of the barrel rather than a more uniform penetration that an apfsds dart would likely bring. If you read my suggestion, i thank you for your time!

what program are you using to simulate?

Could you test 40mm HEDP grenades against a light armored like a bmp/btr or 40mm HEAT against the same targets?

Please give the Dates of when the Projectile and Armours were developed too. In 5 year increments is good enough.

I have an Image of some unique armor. It would be interesting to see it against 40mm Tungsten AP rounds. How could I send that to you?

could you do comparison with and without certain part of armor? with and without porcelain balls

I wonder how it does against subsequent hits. The target is only so large and even spacing the hits out I'm thinking perhaps the damage would mean subsequent rounds had a much easier time going through. Surviving the single hit is good, but given how fast a crew loaded weapon could reload and fire again there may not be enough time to get out of danger before they test your armor package a second time. I think the M60 could get 3-4 seconds and it feels like the head ringing confusion from the round banging your turret (that has to be so loud) might slow reaction time just enough to eat a second round in roughly the same area. Certainly a large section looked compromised on that middle layer.

You help me make a 220mm front armor model.tilt 35° Can you test fire with all the current ammunition? I'm going to research the tank itself.

Kontak-1 vs HEAT would be interesting

i wish there was a comparison to if it was some other type of armor instead of the porcelain

Interesting.

Do a t-30 155mm HE vs Tiger 2 hull deck from shooting the turrets cheek

"The best way to protect an armor is with water" -wise man

It would be cooler if you provided a bit more info on what we are looking at. Usually, a video starts, I try to understand which type if shot hits what type of armour, and the first rendering has already ended. Then the second one is shown, I try to understand what the legend says, and it is already over. If I were you, I would add a bit of an intro on the tank and the ammunition that is being used, then show some simulations, and then add a conclusion as well. Preferrably spoken info.

Who would've thought, the most brittle materials make good armor.

It makes me wonder if you could put these ceramic balls inside a composite metal foam. I'm also interested to see how this works against a modern APFSDS projectile; why is this armour not in use anymore?

Question about armor like this in general. Once it’s hit by a round and the composite materials are destroyed/damaged, how is it repaired if at all?

If a tank somehow survive after a penetration, how does one fix the hole on composite armor? Replacing the whole turret?

Notice how the ceramic balls crack b4 the aluminium is even impacted.

Sorry, but you have the wrong model. Aluminum inserts were used on the T-64. Starting from T-64A new turret was developed with corundum balls in a steel turret - 115 steel cast armor, 140 mm ultra-porcelain balls, and a back wall of 135 mm steel, with an angle of inclination of 30 degrees. The experimental variant used a steel turret with hardened steel(same as in AP rounds) inserts, but this project was shut down due to numerous problems.

Does the aluminium layer ever start to burn?

would be interesting to see how a similar setup of just plain armor would do.

The process of getting those balls placed correctly must been such a ball ache

Could you do a HESH round vs ERA?

Now imagine container just like ERA, but bigger and stronger, and inside such container, instead of explosives you got balls - metal balls (DU maybe?) - at least 3 rows of such balls, rubber walls from inside of container. That balls would let inside any SABOT inside, but smash it, after balls would bounce off rubber on container walls. For science i would try to add grease in whole container. It would weight much, but it could serve much longer than ERA, while being relatively easy to fix. Now imagine whole tank covered with such containers as extra armor. Tracks in type of B1 (overlaying on top of the hull), whole space between track top and road wheel covered with cuch container, same on turret, hull front. Gun mantlet could be covered by such container (with gap only for coax and gun barrel).

Called it!

Literally absord energy

Balls are no joke

Can we see the return hit on the t72b?

what if the projectile hit the gaps between the ball?

pls do porcelain vs quartz core

Can you do 3bm42 vs t72b3 front hull(with era) 1-2km distance just to know how actual war tank duel would go

This is why we love sandwiches

we have porcelain on our dining plates right?

Why did you decide on the Vant round instead of Mango?

Balls of Porcelain

And that, is how you stop an APFSDS without ERA.

can you simulate the "cope cage" with ERA added on top of it?

Brb, gonna turn my toilet into a tank.

What range did you use or was this point blank?

Since some of the energy is dissipated by moving the ceramic ball out of the way I wonder if more energy could be absorbed if the ball were a less hydrodynamic shape and was harder to push through the aluminum?

Try 3BM42 next! Or, can you please, build a simulation of a 76.2mm shrapnel shell with a brand tube set to "hit" on 630m/s agnist 17mm of boiler iron and 15cm of oak or pine wood?

Balls of steel? pfft.. Ive got balls of ULTRA porcelain.

Cool😮

Make a vídeo with a shot in driver windows of Tiger 1, please.

What kind of program?

French during The Great War:

There's ceramic (e.g. porcelain), and then there's ceramic (e.g. silicon or boron carbide). Which is this? What exactly is "ultra porcelain"?

Are you sure this simulation is correct? Its kind of hard to believe 3bm32 couldn't go through even though it was 2.5km distance.

How was calculated speed of inpact? If shell has 1700-1750m/s speed after shooting. Why simulation at 1500m/s?

for some reason I allways thought it's ceramic rods not balls

why dont they just make the infill of armor all porcelain then??

I thought it's understood that 3BM42 can reliably penetrate T-64B across the frontal arc from that range, despite 3BM42 being tungsten rather than uranium (i.e. 3BM32).

like ball inside molten metal?

they were a lot more effective against heat

Whats the programs name?

Would have been more interesting with 3bm42 tbh

niiiiice~~😄 now, wut about without those ceramic balls? do a comparison pls?😉

yes but how did they get those blue lemons in there

Fun note to all those comments below: no, no known NATO tank uses ceramics in main armor. Neither M1 Abrahams, nor Challenger 1/2. It's all a thousand flavors of NERA.

I love this armor. Invincible in its day and still decent in 2023. Of course at distance against a lesser rod.

Now use 3BM60

Stugna go brrrrr

A R M O R E D B A L L S

what software is this?

What is the composition of the ultra porcelain?
