Preliminary: I'm not good with tensor calculus, but it's okay for me to work with reasonably complex differential equations.
What I need is understanding of process of high speed (5-500 km/s) collisions of bodies from real-word materials like metals and silicate minerals: what equations guards processes in idealistic approximations, what processes makes approximations bad (like evaporation of hot enough parts), is there any free academic simulation software for the problem and, if possible, some movies of simulations and experiments of the process.
My level in solid-state and fluid dynamic sciences is zero and and I assume, that proper answer includes list of free or easily available literature/slides/articles to read.
So... Any advise?
