Abstract

This paper presents the results of experimental compression tests on a 2D granular material composed of a mixture of circular and rectangular rods. Numerical simulations of the tests, using a Discrete Element Method (Molecular Dynamics), successfully reproduce the experimental results. The results of the comparison between experimental and numerical results highlights the important role of the contact laws (especially the rolling resistance). A statistical study of the rotations of
rectangular particles during compression (experimental and numerical) is carried out. The results of such study are finally compared to the predictions of continuum mechanics.
