Granular friction, Coulomb failure, and the fluid-solid transition for horizontally shaken granular materials.
We present the results of an extensive series of experiments, molecular dynamics simulations, and models that address horizontal shaking of a layer of granular material. The goal of this work was to better understand the transition between the "fluid" and "solid" states of granular materials. In the experiments, the material-consisting of glass spheres, smooth and rough sand-was contained in a ...
متن کاملEshelby Transformations, Pore Pressure and Fluid Mass Changes, and Subsidence
This paper is motivated by a recent analysis by Walsh (2002) of subsidence above a planar reservoir. Although the problem has been treated previously by Geertsma (1966, 1973a, b) and Segall (1992), Walsh (2002) uses a different approach. In particular, he uses a cut and weld procedure, originated by Eshelby (1957), and the reciprocal theorem of elasticity. Walsh obtains the same results as Geer...
متن کاملLangevin equation with Coulomb friction
We propose a Langevin model with Coulomb friction. Through the analysis of the corresponding Fokker-Planck equation, we have obtained the steady velocity distribution function under the influence of the external field.
متن کاملConsolidation and Pore Fluid Pressure of Ursa Sediments, Deepwater Gulf
15 We conducted uniaxial compression tests on whole core samples from the Ursa 16 Basin, deepwater Gulf of Mexico, to obtain the consolidation properties of mudstones. 17 We showed that specific volume (v = 1+e) (where e is void ratio) declines as an 18 exponential function of effective stress and we used this relationship to successfully 19 predict in-situ pressure from void ratio at IODP Site...
متن کاملPore pressure and poroelasticity effects in Coulomb stress analysis of earthquake interactions
[1] Pore pressure changes are rigorously included in Coulomb stress calculations for fault interaction studies. These are considered changes under undrained conditions for analyzing very short term postseismic response. The assumption that pore pressure is proportional to faultnormal stress leads to the widely used concept of an effective friction coefficient. We provide an exact expression for...
