Ultrasonic Study of Water Adsorbed in Nanoporous Glasses
Jason Ogbebor, John J. Valenza, Peter I. Ravikovitch +6
Thermodynamic properties of fluids confined in nanopores differ from those observed in the bulk. To investigate the effect of nanoconfinement on water compressibility, we performed…
Stress-dependent normal mode frequencies from the effective mass of granular matter
Yanqing Hu, David L. Johnson, John J. Valenza +2
A zero-temperature critical point has been invoked to control the anomalous behavior of granular matter as it approaches jamming or mechanical arrest. Criticality manifests itself…
Frequency-dependent attenuation and elasticity in unconsolidated earth materials: effect of damping
Yanqing Hu, Hernan A. Makse, John J. Valenza +1
We use the Discrete Element Method (DEM) to understand the underlying attenuation mechanism in granular media, with special applicability to the measurements of the so-called effec…
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…
