Systematic numerical simulations of model dense granular materials in monotonous, quasistatic deformation reveal the existence of two different r\'egimes. In the first one, the macroscopic strains stem from the deformation of contacts. The motion can be calculated by purely static means, without inertia, stress controlled or strain rate controlled simulations yield identical smooth rheological curves for a same sample. In the second r\'egime, strains are essentially due to instabilities of the contact network, the approach to the limits of large samples and of small strain rates is considerably slower and the material is more sensitive to perturbations. These results are discussed and related to experiments : measurements of elastic moduli with very small strain increments, and slow deformation (creep) under constant stress.
