Jamming Transition in Granular Systems
Jamming Transition in Granular Systems
Recent simulations have predicted that near jamming for collections of spherical particles, there will be a discontinuous increase in the mean contact number $Z$ at a critical volume fraction ${\ensuremath{\phi}}_{c}$. Above ${\ensuremath{\phi}}_{c}$, $Z$ and the pressure $P$ are predicted to increase as power laws in $\ensuremath{\phi}\ensuremath{-}{\ensuremath{\phi}}_{c}$. In experiments using photoelastic …
