Stresses in silos: Comparison between theoretical models and new experiments
arXiv:cond-mat/9904094 · doi:10.1103/PhysRevLett.84.1439
Abstract
We present precise and reproducible mean pressure measurements at the bottom of a cylindrical granular column. If a constant overload is added, the pressure is linear in overload and nonmonotonic in the column height. The results are {\em quantitatively} consistent with a local, linear relation between stress components, as was recently proposed by some of us. They contradict the simplest classical (Janssen) approximation, and may pose a rather severe test of competing models.
