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…
Tortuosity Measurement and the Effects of Finite Pulse Widths on Xenon Gas Diffusion NMR Studies of Porous Media
R. W. Mair, M. D. Hurlimann, P. N. Sen +3
We have extended the utility of NMR as a technique to probe porous media structure over length scales of ~ 100 - 2000 micron by using the spin 1/2 noble gas 129Xe imbibed into the…
Packing of Compressible Granular Materials
Hernan A. Makse, David L. Johnson, Lawrence M. Schwartz
3D Computer simulations and experiments are employed to study random packings of compressible spherical grains under external confining stress. Of particular interest is the rigid…
Why Effective Medium Theory Fails in Granular Materials
Hernan A. Makse, Nicolas Gland, David L. Johnson +1
Experimentally it is known that the bulk modulus, K, and shear modulus, μ, of a granular assembly of elastic spheres increase with pressure, p, faster than the p^1/3 law predicted…
