High compression of granular assemblies of brittle hollow tubular particles
M. Stasiak, G. Combe, V. Richefeu +2
This paper is devoted to the micro-mechanical origins of the high compressibility of brittle tubular particle assemblies. The material is extremely porous due to the presence of a…
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…
