Experimental validation of nonextensive scaling law in confined granular media
Gaël Combe, Vincent Richefeu, Marta Stasiak +1
In this letter, we address the relationship between the statistical fluctuations of grain displacements for a full quasistatic plane shear experiment, and the corresponding anomalo…
Jamming transition in a two-dimensional open granular pile with rolling resistance
Caio F. M. Magalhães, Allbens P. F. Atman, Gaël Combe +1
We present a molecular dynamics study of the jamming/unjamming transition in two-dimensional granular piles with open boundaries. The grains are modeled by viscoelastic forces, Cou…
Mechanical properties of inclined frictional granular layers
A. P. F. Atman, P. Claudin, G. Combe +1
We investigate the mechanical properties of inclined frictional granular layers prepared with different protocols by means of DEM numerical simulations. We perform an orthotropic e…
Polygons vs. clumps of discs: a numerical study of the influence of grain shape on the mechanical behaviour of granular materials
K. Szarf, G. Combe, P. Villard
We performed a series of numerical vertical compression tests on assemblies of 2D granular material using a Discrete Element code and studied the results with regard to the grain s…
Particle shape dependence in 2D granular media
B. Saint-Cyr, K. Szarf, C. Voivret +9
Particle shape is a key to the space-filling and strength properties of granular matter. We consider a shape parameter describing the degree of distortion from a perfectly sphe…
An experimental assessment of displacement fluctuations in a 2D granular material subjected to shear
Vincent Richefeu, Gaël Combe, Gioacchino Viggiani
In a granular material, a macroscopically homogeneous deformation does not correspond to a homogeneous displacement field when looking at the individual grains. The deviation of a…
