Long-term behavior of Hertzian chains between fixed walls is really equilibrium
Long-term behavior of Hertzian chains between fixed walls is really equilibrium
We examine the long-term behavior of nonintegrable, energy-conserved, 1D systems of macroscopic grains interacting via a contact-only generalized Hertz potential and held between stationary walls. Existing dynamical studies showed the absence of energy equipartitioning in such systems, hence their long-term dynamics was described as quasi-equilibrium. Here, we show that these …
