Energy transference at hypersonic velocities

Im pretty certainly we have had this discussion before so Ive got one of my old copycats from a previous thread. Force travels through solid objects at roughly the accelerate of sound in that object, if you cast a piece of an object to function at greater than the whet of sound through that medium it leave behind simply tear whatever is holding it together with come in transmitting military strength to the surrounding structure. His gives a kind of hole punch effect If the dynamic Is moving faster than the speed of sound In the target. The maximum cognise speed of mound is about 1 km/s in diamond, given that a dreaded shot moves at about Kim/s it is safe to assume that fit anti going to do sit. prone the momentum behind the small slug it should remain above the speed of sound in diamond until (keg*Kim/s/km/s) the total jam of matter it has punched through reaches 5. 3 tones.Second, lithesomegs heat up when they are two-dimensional as given by the perfect gas law (at th ese vitality densities it is close enough for our purposes despite everything being solid) so when the projectile gets fuddled it heats up, if it heats up to the correct bevel it melts, vaporizes and turns into plasma, that dep give notices on the energy densities present (FUSION). So when a solid slug hits the armor the first thing which will happen Is that the slug punches a hole clean through the armor, no ifs, no buts.Then the haul roll up begins to propagate through both the armor chunk which has been torn out and the projectile, the amount of pressure in this wave is so immensely fugue that the matter instantly fashions plasma dead followed by becoming a angular fireball. The only question remaining is how far does the projectile reach inside the ship until you can die imitate It as a projectile and have to start modeling It as a nuke. He Irony here Is that armor essentially contains the fireball Inside the vessel Instead of keeping it on the outside. This is besides why whippier shields are effective, the small layer of matter makes a hyper velocity impact under go the pressure induced explosion and become a far less damaging gas which Is then repelled by the actual armor of the vessel. Than artillerys are a whole different ballgame. across the nation what comes out of a Than weapon can be considered a plentifulness driver slug (the fact that it is molten doesnt tater, the impact velocity is so far beyond the speed of sound in the target and projectile that its irrelevant) but in this case instead of being a CACM wide cylinder or even a Javelin It is a long thin wire which probably only has a cross section deliberate In tenths of millimeters and a length In the hundreds of meters. ND punches a hole, the pressure wave propagates back through the projectile, as the pressure wave diges it explodes with the force of a nuclear weapon. So far normal. BUT Because the projectile is so long and traveling orders of magnitude faster than its peed o f sound, once the front end explodes it leaves relatively clear (exploded) space for the next section of the projectile to pass through anus strike deeper into the target, Just like a pulsed laser or a multiple impact kinetic weapon like alloy storm. His happens over and over and over again, the end effect is that a Than weapon will punch clean through a ship and out the other side which leaves a nice neat little hole.
