HESH vs Composite Armor | T-72 |Armor Penetration Simulation

HESH shell simulation vs Composite Armor.

155MM HESH at 680 m/s
Explosive - 11.7kg Comp. A-3
The weight and type of the explosive correspond to the 155mm HEP T152 projectile (T58 Heavy Tank shell)

Vs

T-72 hull front armor

60mm RHA
2 x 52mm glass textolite
50mm RHA

In fact, the armor worked because no large pieces of armor were ejected. A homogeneous armor plate would not stand a chance.

It is surprising that the base of the projectile was still almost intact and moving forward after the explosion, nice work!

[moosiemoose]

Wow! That would be absolutely terrifying.

Great simulation as always!

[KekusMagnus]

resisted much better than a pure 110mm RHA plate would have, composite armor definitely works. The driver may be wounded but the tank would probably be fine

[Phapchamp]

Tanked it like a boss. Considering the huge difference between 120/105mm and 155mm HESH i think T-72 was really well protected against HESH. I wonder about the interaction between ERA and HESH but i suppose i can never see that.

I was surprised about result because I’ve expected textolites would completely absorb the HESH, but as the result, energy of detonation transmitted something like a Newton’s cradle.
This is probably one of the reasons why some spaces added in the constructions of later T-72s’ composite armors

I would be glad to see the damages done to the insides of the tank, just like in the miniature. I know it is much more complicated but it is the next step into the simulation.

Are there any experiments or estimates for low velocity impacts?
For instance, if a 50 ton tank rams a light tank with only 20mm armour, or when a building collapses onto the tank...
I know that there's data on driving over trees and into walls. An acquaintance was stuck in a tank in WWII when they tried to hide their tank from an air raid and parked it inside a hall next to a church. The enemy bombed the church and the tower fell onto the hall and their tank...

working as intended! Belt just ended up buckling really hard. (drivers going to be scared shitless at all that deformation, at least its not like the APFSDS video where he lost his head completlely)

[PikaPilot]

This is a fascinating simulation! The armor successfully prevented damage from getting to the crew, but it absolutely would not survive a second shell.

The HESH damages a large area, which deforms the armor far more extensively than solid AP would.

[xXxNECROMONGERxXx]

I wish this video had a witness plate to see how badly the spalling would damage a tank occupant. That armor deformation looks brutal on the interior. Thanks for the simulation!

[danielwer]

Wow, ive never expected that hesh will be that effective

[Forbiddina]

Yep, a 6 inch shell hurt it pretty bad. But it’d probably do just fine for the calibers that it was intended to block 105/120mm.

I’m still curious how much that would screw up the rest of the sensitive systems. But that’s beyond a simple simulation

[Wolfy]

Driver: I don't think I want to be a soldier anymore

[arkrainflood]

question: what kind of damage does a hesh blast wave do to components of a tank? (antennas, optic sights, lights, calibration of various control systems)

might the blast wave distort the barrel even a little to compromise its accuracy?

[akula]

The shock wave inside the vehicle would incapacitate the crew.

[Fms_procent]

Its old composite armor. The new one has five layers: 3 metal plates and two glass textolite

[snoohh]

Nice video request answered, HESH is way more effective than i thought it would've been.

[btall]

Remember, it's not always about definitive penetration. The concussive effects of HESH (or even regular artillery) can wreak havoc on the crew or the tank's internal systems.

[jojomojo]

Can you please simulate a BR-412 hitting the turret cupola (commander optics) of any tank (for example, M48)? Including a filler explosion.
