“…We remark, in addition, that even for piles of axisymmetric particles, i.e., two-dimensional stacks of homogeneous and isotropic cylinders, not much work has previously been done regarding their stability [5,6,13].…”

“…The mechanical stability of granular piles has been the subject of numerous studies, both experimental and theoretical [1][2][3][4][5][6][7][8][9][10][11][12], and it has been found to depend on various factors: the number of grains, packing fraction, history, boundary conditions, and cohesion, particularly due to humidity. Also, the maximum slope that the pile can exhibit depends on the shape of the grains, on the physical properties of their surface (for instance on the roughness), and on the distribution of their size [13][14][15][16][17].…”

Avalanches of grains with inhomogeneous distribution of inner mass

We study the stability of granular systems constituted by particles with inhomogeneous distribution of inner mass, which is a factor that has not been previously analyzed. In particular, we report experimental results concerning the stability of two-dimensional piles of hollow plexiglass cylinders containing an inserted smaller metal rod. These particles partially fill a rough-edged drum whose rotation produces successive avalanches. The distribution of the maximum angle of stability, the angle of repose, and the avalanche size are analyzed for systems in which the inserts are fixed or free to move. We reveal two interesting effects related to the nonuniform inner mass distribution. On the one hand, the disorder in the array of the center of mass, enhanced in the system of particles with a fixed insert, decreases the stability of the pile. On the other hand, both mobile or fixed inserts lead to larger erosion of the free surface once the avalanche is triggered.
