Temporal correlation of force and position in granular materials

We investigate the quasi-static mechanical response of dense granular materials under biaxial compressions by using discrete element simulation. The internal force network and its evolution are observed for different strains. Our results show that correlation of force and position appropriately characterize the bulk response and volumetric strain.
