The title inside the video should read Shaped charge in stead on Shape charge. Sorry about the typo. Addendum: What's not emphasized in this video is the Standoff. The standoff is the distance from the base of the liner or cavity to the target. At this this distance the jet from the shaped charge will have the greatest effect on the target. Shorter than the standoff distance, the jet may not fully form. Longer than the standoff distance, the jet may break up and greatly reduce the penetrating depth.

Funny thing about shaped charges: alot of people think that the metal being expelled is liquid because it got melted; but in reality, the metal isnt hot enough for that. The reason it's liquid is because the forces/pressure is so incredibly high, that the metal simply acts like a liquid.

The melting point of copper is 1085 degC. It’s known that increasing pressure on a substance will increase the temperature at which it will melt, so with the incredibly high pressure exerted by an explosion, the copper isn’t actually liquid. But it remains malleable, and so will deform into the narrow penetrator that defeats armor plate. Between the copper itself, the spall of the armor, and the blast effect that accompanies it, some very unpleasant things will happen inside that target vehicle.
@alexholker13093 жыл бұрын
Nice little video. I think the most interesting thing about shaped charges is how counterintuitive the explosively formed penetrator's behaviour is. The naive assumption would be that a narrow charge placed directly against the target would produce the most effect, but either of these things wouldn't give the shaped charge room to form the jet of metal that actually does the cutting.

It looks like shaped charges were used to make the diagonal cuts in the columns of the twin towers on 9/11. In some of the collapse videos you can see hundreds of very fast streaks of white light emanating from the collapse area. The buildings fell at nearly free fall acceleration, so it's clear that the columns were "taken out". If the structure were intact, t's impossible that the buildings would collapse through the path of greatest resistance, which was the steel structure designed to support 5 to 10 times the building's weight.

I'm not an expert but I'd assume the self lubricating aspect of copper helps it flow and jet under pressure more easily and accurately. One of the reasons why it works as a bullet jacket material so well. Graphite is a good dry lubricant for the same kind of reason. The particles slide past each other smoothly without hanging up. Its a pretty cool effect. Colloidal liquid/grease type lubes with high solids amounts usually contain lots of very fine copper to take advantage of this effect. I think Geisselle has a gun trigger lube like that if I remember correctly.

The solid state hardness of the material used isn't really important, whats important is the pressure/force driving it being greater than the resistance offered by the material it's being driven into.

Well simply shaped charge munition back then wasn't as researched as now, and also was more crude and unreliable, for example there was an attempt to up-gun the sherman, also known as the M4A3/M4A1/M4A2's 105mm Howitzer, it had a HEAT round called the M67 which can only penetrate around 130mm of RHA, meanwhile the Abram's 105mm M456a2 shell can penetrate up to 400~450mm of RHA. Another example would be Germany L/48 guns mounted on Panzer 4's, their HEAT was so crude it only penetrated about ~80mm of RHA. Other than that, the effect of these shaped charges were also reduced due to it spinning thus the copper liner losing the ability to form the jet properly. At least what I know, correct me if I'm wrong.

@@Howleebra No, heat or heat-transfer are not major influences when it comes to depth of penetration at these velocities. There is some influence of heat on yield-strength (and density) of the material and in that way it does play a role in penetration. There is also an influence of heat when it comes to the formation of the jet. Here it gets really complicated but it boils down to how big the jet gets before breaking up and how long the tail of the jet is (bigger jet means more mass impacting the target -> more penetration). But overall, the penetration is over too quickly for heat-transfer to play a role. We are not burning or melting our way through a target; we are pushing through. We apply about a few 100 times more force than the material can sustain. So it will yield and do so in such a way that it appears as if it is fluid (as if it doesn't put up any resistance). Studies have shown that the material after impact showed large grain-deformations (elongation). If the material was melted and re-solidified, it would show new grains that are round-ish. Hope this helps understanding the physics involved.

You're wrong. The liner has essentially no effect on penetrtion. So long as an optimal 42 degree cone is maintained, and the target has a stand off distance of 2/3 diameter, the force of the explosion focused into a much smaller area is what causes shaped changes to penetrate. Fun fact: the cone shape in bottom of fat Gatorade bottle is 44 degrees, almost perfect for a shaped charge. Packed full of c4 and double primed, this ied will cut through steel even though the only metal in it is the aluminum blasting caps. I've literally made dozens of these, and they work great with a plastic liner. The whole 'zomfg liqud metal jet' is an often repeated trope about sc, but it's nonsense.

What is the effective range and why isn`t this used in rifles? I mean it`s around atleast since ww2 and used in antitankmines that look like a rocket launcher and shoot from the side.

Shaped charges are meant to be detonated on the surface of the target, passed a couple feet it would lose most of its energy

@@bop3752 Doesn`t it fly ridiculous fast? and straight enough. There was a german politican who was killed by RAF (Rote Armee Fraktion) back in the day with one as a roadside bomb on a bilke or something like that. Should be fast enough for modern body armor, light vehicles and walls. That`s just my guess though. When in the military on an introduction to exlosives we cut through the motorblock of a car with one.

Also when you watched well I don't know your taste, "the last air bender", or "Twilight" and you found one to be BS, you did not go out and made one of your own you just warned your buddies.
