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…
Mechanical response of an inclined frictional granular layer approaching unjamming
A. P. F. Atman, P. Claudin, G. Combe +1
We present an orthotropic elastic analysis of frictional granular layers under gravity by studying their stress response to a localized overload at the layer surface for several su…
