Dynamic effective mass of granular media and the attenuation of structure-borne sound
John Valenza, Chaur-Jian Hsu, Rohit Ingale +3
We report an experimental and theoretical investigation of the frequency-dependent effective mass, , of loose granular particles which occupy a rigid cavity to a give…
Dynamic effective mass of granular media
Chaur-Jian Hsu, David L. Johnson, Rohit A. Ingale +3
We develop the concept of frequency dependent effective mass, M(omega), of jammed granular materials which occupy a rigid cavity to a filling fraction of 48%, the remaining volume…
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…
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…
