Abstract
The random packing of identical hard disks generated by a ballistic model with complete restructuring has been investigated. The density of defects (i.e. particles having a number of contacts different from 4) was found to decrease as a power law with the distance from the bottom of the packing in the limit of very large distances. In the asymptotic very large height regime, a random structure without defect was found which is characterized by a broad angular distribution for the orientations of the bonds between contacting disks.Keywords
