This paper is a short comment about the paper "stress propagation and arching in static sandpiles" by Wittmer, Cates and Claudin [1]. It concerns the validity of the radial stress field (RSF) scaling assumption used to calculate the stress distribution in a conic granular material and its agreement with different experimental data.

On discute la validité de l'hypothèse d'un champ de contrainte radial utilisée par Wittmer, Cates et Claudin [1] pour prédire le champ de contrainte dans un milieu granulaire cônique.
