Abstract
From a first principles theory for the behavior of smooth granular sys tems, we derive the form for the instantaneous dissipative force actin g between two grains. The present model, which is based on the classic al harmonic crystal, reproduces the dependence of the kinetic energy d issipation on the grain deformation obtained by models that assume a v iscoelastic behavior (without permanent plastic deformations) during t he collision.
