Numerical Study of the Stress Response of Two-Dimensional Dense Granular Packings
N. Gland, P. Wang, Hernan A. Makse
We investigate the Green function of two-dimensional dense random packings of grains in order to discriminate between the different theories of stress transmission in granular mate…

Granular Packings: Nonlinear elasticity, sound propagation and collective relaxation dynamics
Hernan A. Makse, Nicolas Gland, David L. Johnson +1
Experiments on isotropic compression of a granular assembly of spheres show that the shear and bulk moduli vary with the confining pressure faster than the 1/3 power law predicted…
