KV-2 vs Panzer IV | Armor Penetration Simulation 

Lately, I've seen oddly specific areas shells hit. I have this feeling this guy played Warthunder and went like "THAT BS! I bet that wouldn't have bounced!" And learned advanced physics simulations only to rant on gaijin lol.

I dream of the day where simulations like these will be possible to implement in video games

Would there be a way to show the pressure wave of the explosion entering the vehicle? That would look really cool especially for how much HE is present.

While this still would be deadly for the crew, I'm surprised the explosion made such a small hole instead of vaporizing the top plate.

HE sims are the most interesting imo

Great vid as always Dejmian, I had no clue I was interested in KV-2 hitting Pnz IV until now. Attempt #X: Panzer III M/L 50mm shell vs front of T-34 or KV-1

Rip Hanz Also ty for all these simulations, it's really interesting and informative

Thank you for your WW2 vids, they are all very interesting.

Same time in WT: gun barrel broke. Same time in WoT(b): -273 hp

I read about a confrontation between a Tiger and an Isu152 before. The Tiger shot first but missed while the Isu152 blew off the Tiger’s turret, not ammo racked but just with sheer force of the HE blast, the Tiger was still able to reverse back to German line.

From that angle most of the shrapnel inside the tank would have hit the transmission. Hanz has a new transmission to repair once he's done with the Panther for the thousandth time.

Don't worry, its just the driver that has gotten his legs shredded off and is now bleeding out, I'm sure he'll be fine, its just the driver after all.

Wonder how would the T-80U turret (strongest armor in the channel) be up against Yamato (strongest shell in the channel)

Surprised it didn't do as much as I thought it would. There's images of Panthers with half their turret broken after being hit by a 152 mm HE shell.

I love this channel! Keep up the great work!

Amazing as always! Can we get a kv2 HE on panzer IV cupola? Id love to see this effect on the turret

My understanding is that common practice was to remove the fuse before firing at vehicles. That kept all of the kinetic energy intact, especially when striking a more vertical surface. You might lose the detonation, but having high explosive scattered around the inside of the target tank was adding insult to injury.

When you look at this video you may think "ah only the driver and the radio operator are dead, the gun still works!" But it's not true. The pressure from an immense shell would cook the men inside like an egg. I've heard of an Elephant (or Ferdinand) getting shot by HE that the crew died sooner than the vehicle, despite there being no signs of penetration. Would be an interesting video if such pressure could be shown.

I thought 152 would have waaay greater effect

KV2 or ISU 152mm HE was able to penetrate 50-60mm of steel. so thats means that will rip of PZ4 top armor like paper when it hit like that

The dudes skull when he is tricked into head butting a concrete ball after I make it look like a soccer ball.

So on that shot the tank will be completely immobilized since the sharpnels and pressure damages the transmission completely. Although driver will died instantly while others can be fatal because of the pressure. Also in Tank Battle simulator games on KV2 against PZ4: Warthunder: Sends you back to garage WoT: 10~20% survival chance. Wot(B): instant garage Wot(Console): Guaranteed instant garage (blaming pre-1.9 patch HP)

Hi Dejmian! Could you consider doing a shaped charge (simplified RPG-7 model maybe?) vs T-64B/T-80B hull? Would be interesting to see how the multiple steel-textolite layers interact with the shaped charge jet because that's what they were designed to defeat :-)

RIP the driver and MG gunner because even if they survive the blast pressure inside the shrapnel is likely to have killed them.

Похоже что данная симуляция неточна. Реальный снаряд рвал в клочья и выводил из строя практически любую технику .

That would also probably crack the welds between the plates and cause an even bigger hole.

Was surprised. Expected something... bigger.

I can hear the WoT voiceover yelling “penetration” in my head

What are your computer specs? Does it take a lot of hardware to process these simulations?

Привет ! Мне кажется ты не правильно задал условие.Пластины обычно сваривают между собой а на видео они не сварины из-за этого жëсткость конструкции меньше, можешь перемоделировать? Очень интересно что же получится!!!!

Wow I expected so much more damage from such a large shell

I see the fragmentation is more or less uniform and in aproximately equal weight pieces. As far as i know there should be some bigger pieces, especially coming from the back of the projectile.

Hi! May I ask what software you used to simulate this? And I have to say that being able to model the shell going off is really impressive!

One of the more interesting mechanics of armor penetration is when a plate can resist the detonation but the mass of the impact simple overwhelms the armor. The 152mm cannon would be capable of killing many a modern tank if it hit in the correct location. And by correct I mean if it detonates over the top of the hull or turret. The explosive force is more than most tanks are designed to take.

From what it looked like, most of the fragments traveled roughly towards the transmission. (but potentially still deadly towards the driver and machine gunner, not to mention the massive pressure/shock wave that they would be hit with) But my question is, do you think that the shock/pressure wave would still be potentially deadly towards the crew in the turret?

War Thunder: oVeR pReSsUrE iNiTiAtEd

Makes me wonder about the effectivness of smaller HE shells. Could you test a Russian 76mm HE shell against the lower part of a T-34s turret? Apperently it would penetrate the 20mm hull roof armor. In WT most 75/76mm shells can't even penetrate a M18, while Soviet AT hand grenades with ~700g TNT were suppose to penetrate 20-25mm of armor.

I just adore that little moment where loose polygons went looking like the simulation program was a Garry's Mod

According to war thunder: 1 explosion that goes through the armour: entire crew dies

КВ 2 ❤

The front plate seem to be unimpressed :). Could you simulate same HE shell hitting same vehicle/armor setup at two different velocities ? IIRC the Russian did (after Ww2?) some tests of what affect armor penetrating ability of HE shell and to the surprise it came out from tests that kinetic energy of the shell was a big factor. Same 122mm HE shell would be able to penetrate very different plate thickness at 500m/s than at 700m/s. I wonder if this is really depending on added kinetic energy/momentum of shell mass. Sadly I don't have a link for that at hand. I also wonder if any fuse setting other than "instant" is possible against armor (other than really thin plates) or the fuse would be destroyed and not work at during penetration.

На сколько достоверны эти симуляции?? Мне кажется после попадания фугаса кв 2 там повреждения были бы гораздо страшнее

Kv2 just has too much explosive for early armor haha. I'd love to see some simulations of HMG rounds against light skinned vehicles, e.g. 12.7x99 vs btr or 14.5x114 vs Stryker

Yea, The second I read that title I immediately knew the outcome would be obliteration.

I feel like every one of these simulations is a bounce you got on War Thunder and you are just trying to prove that it would have penned.

IS-2 122mm using APHE vs Jumbo armour

Что-то мне кажется, но 152 болванка при прямом попадании по такой тонкой броне просто разорвет всю переднюю часть в хлам, оставив кратер :D

what about an anti concrete shell of the kv-2

I am wondering if you could do some medieval stuff , like arrows , crossbow bolts or early firearms against steel breastplates/helmets ?

Damn thing nearly went through with sheer mass, the couple pounds of HE filler were just insult to Inhury

Cool! What program did you use?

I honestly expected the front plate to be almost entirely shattered, interesting...

That’s crazy that that top plate was only 20mm. Looks like a death trap.

Sorry for the Google translator. There is a lot of talk about the poor quality of Soviet shells. Allegedly, their real armor penetration was lower than stated. I think many people would be interested to see how the armor penetration of the over-heated and under-heated projectile will change.

Ah, just a little flesh wound, i can still fight. -Black knight.

Shrapnel anyone? Driver? Driver?

Can you do AT3 Sagger/malyutka against a frontal armor or weak spot of an M60 Patton? I'm curious about the effectiveness of the weapon against its probably most advanced adversaries at the time because it is often seen as obsolete relegated to its shape and launch platform

Tbh the explosion was kinda underwhelming. I thought it was gonna completely vaporize the plate, I mean its a 152mm HE

My toe when I hit the corner of the table

Still ripped off the thin armour

if you open the tank you will find the crew who has been turned into biomatter

[Simulation run time: 0.002s] [Result: yeah they're dead bro]

If that upper plate was just a little bit thicker I wouldn’t hate the Panzerkampfwagen IV as much

I got into a discussion with my buddies whether the German pz IV armored screens are able to protect the tank from hitting the 152mm HE with the KV-2. Could you make a simulation of this? Will the explosion be large enough to cause ovepressure?

That's gonna be awfully inconvenient inside the tank next time it rains.

Seeing how much damage the shell was doing to the armour before it exploded, I'm somewhat curious how this situation would play out if the shell was a dud and didn't explode.

I will have to say that this one is not close to realistic explosion. There is a photo of a direct hit of a panther turret by a 152mm shell shot from SU-152. It was an absolute carnage.

I used to be an adventurer like you, then i took a 152mm to the transmission.

What about running armored vehicles into barriers? What happens if a BMP hits a tree?

Crew members surely didn't enjoy that.

Hey man what is the pc build and software you use to run these calculations/ experiments?

When life give you lemon , you make HE

The Russian Bias is stronk on the Russian Fridge Tank

The KV-2 shell explosion in WT is 10 times bigger than the one we see here

i m surprised, i would have expected the welds to snap and the plates to be yeeted far away

Interesting. Is the weld breaking or is it sheared off?

20mm seems inadequate to stop anything bigger than rifle round even for a pre war tank

Let me guess, someone was pissed their KV-2 didn't knock out said Panzer IV with said HE in War Thunder, and wanted to see if the simulation would say otherwise.

Crew have no chance to survive, because shell explode and crew are shocked and then die

What would happen if a Pork Pie weighing .5Kg travelling at 1600m/sec hit the armour?

god dammit hans! our transmission is down!

Honestly I'd be curious to see if the shell hit under the the turret, like the ring. The damage would seem interesting to me at least

Who would win, a full panzer division, a group of weird refrigerators

It would be a bad day to be the driver, but the rest of the crew would probably be alive - if badly rattled.

King Tiger vs T72

can you make some simulations in realtime? that would be nice.

Is there a difference between this shot and one on the flat pieces of armor?

“CREW KNOCKED OUT”

Me personally, I wouldn’t let nobody have on 20mm of armor right there

The driver and radio operator is in a bad day after that

German long 75mm AP vs KV-2 frontal hull next

Does the sim calculates the pressure wave or just generates tons of fast moving shell pieces?

I think that if you are hit with a 152 HE shell you are probably having a bad day anyways

Rest in pieces Hans

So, the crews are toast.

I am assuming this simulation is done in a vacuum. It would be good to simulate at 1 Bar air pressure.

Ah, the derp cannon.

All my warthunder experience tells me that the Pz IV would be VAPORIZED.

Can you do artillery shell on top of T-64/T-72/T-80 ?

Can you show how this Explosive impact to crew inside. I mean see their body getting wreck and cook alivr 😀
