Description

We discover that the apparent weight and the electrical resistance of randomly packed stainless steel balls exhibit unusually slow relaxation behavior. It is found experimentally that these relaxations are due to structural change of the packing. Simultaneous measurements of the apparent weight and the electrical resistance show correlated time dependence. We have also performed two-dimensional molecular dynamics simulations and studied a possible mechanism for the slow relaxation behavior observed in experiments
