A collision model generally requires the definition of the force F exerted between the two molecules being considered. This force is actually repulsive at short distances and weakly attractive at large distances. Different approximated models are proposed to describe this force. The classic one is the...
While the relationship of the debris cloud expansion speed and the plate thickness was considered, Piekutowski [11] proposed an apparently similar definition of a critical thickness where the debris cloud achieves the maximum expansion and the projectile has a maximum fragmentation. In fact, the two...
In particular, this gives a possible sieve among Delone sets to be crystals in the new definition of a crystal by the IUCr in 1992. Ponctual scaling laws and the Bombieri–Taylor argument are considered.doi:10.1016/S0921-5093(00)01303-4Jean-Louis Verger-Gaugry...
