| Résumé : | We discuss the microstructural origin of stress tensors for granular materials in the context of "non simple" continuum models, of the micropolar and of the second-gradient type. Stress tensors are looked upon as generalised forces in the sense of analytical mechanics and we derive expressions that provide estimates of these quantities on the base of forces and couples exchanged between the grains in a Representative Elementary Volume (REV). |
