I was thinking and the following question came out:
how an object that is falling is simulated once it hits the ground?
Specifically, I would like to understand how one would be able to simulate the cracking of the object, and its consequent breakdown in several pieces.
As far as I understood, this topic is quite important in computer games, but I was wondering how this things are studied in physics.
One approach I recognized was the use of meshes and continuum physics. On the other hand, a N body problem where the particles were "glued" could also work.
Does anyone knows what are the principles of crack formation and object breakdown in this sense?
