Zusammenfassung
The evolution to the steady state of a granular gas
subject to simple shear flow is analyzed by means of computer
simulations. It is found that, regardless of its initial
preparation, the system reaches (after a transient period lasting a
few collisions per particle) a non-Newtonian (unsteady) hydrodynamic
regime, even at strong dissipation and for states where the time
scale associated with inelastic cooling is shorter than the one
associated with the irreversible fluxes. Comparison with a
simplified rheological model shows a good agreement.
