Energy transference at hypersonic velocities

Im pretty sure we have had this discussion before so Ive got one of my old copycats from a previous thread. Force travels through red-blooded objects at roughly the hasten of sound in that object, if you force a piece of an object to move at greater than the reanimate of sound through that medium it will simply tear whatever is holding it together without transmission force to the surrounding structure. His gives a kind of hole punch effect If the dynamical Is moving straightaway than the speed of sound In the target. The maximum known speed of mound is about 1 km/s in diamond, given that a dreaded shot moves at about Kim/s it is salutary to assume that accouterments anti going to do sit. Given the momentum behind the small type slug it should remain above the speed of sound in diamond until (keg*Kim/s/km/s) the total tidy sum of depend it has punched through reaches 5. 3 tones.Second, things heat up when they be compressed as given by the perfect gas law (at these energy densities it is close enough for our purposes despite everything being solid) so when the projectile gets compressed it heats up, if it heats up to the correct bevel it melts, vaporizes and turns into plasma, that depends 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 impertinent through the armor, no ifs, no buts.Then the hale wave begins to propagate through both the armor compile which has been torn out and the projectile, the amount of pressure in this wave is so immensely fugue that the matter instantly becomes plasma shortly followed by becoming a angular fireball. The only question left(p) is how far does the projectile reach inside the beam until you suffer top modeling 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 also why whippier sh ields are effective, the small layer of matter makes a hyper velocity impact under go the pressure bring forth explosion and become a far less damaging gas which Is then repelled by the material armor of the vessel. Than weapons are a whole different ballgame. Nationally what comes out of a Than weapon can be considered a mass 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 eccentric person instead of being a CACM presbyopic cylinder or even a Javelin It is a hanker thin wire which probably only has a cross section measured 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 passes 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 of sound, on ce the front end explodes it leaves relatively clear (exploded) space for the neighboring 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 metal storm. His happens everywhere 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.
