Quasicontinuum descriptions of rarefaction and dispersive shock waves in Fermi-Pasta-Ulam lattices with Hertzian potentials
{{output}}
In the present work, we review two well-established quasicontinuum models of a Fermi-Pasta-Ulam lattice with Hertzian potentials, and we utilize these two models to approximate the discrete dispersive shock waves which are numerically observed in the simulatio... ...
