pore water pressures in three dimensional slope stability analysis
although some 3d slope stability algorithms have been proposed in recent three decades, still role of pore pressures in three dimensional slope stability analyses and considering the effects of pore water pressure in 3d slope stability studies needs to be investigated. in this paper, a limit analysis formulation for investigation of role of the pore water pressure in three dimensional slope sta...
متن کاملDeep Pore Pressures and Seafloor Venting In
The pore pressures of the S, R, Q and P sands follow the hydrostatic gradient and are in pressure communication across the entire Auger basin, Gulf of Mexico. At the structural crests of these sands the pore pressures exceed the least principle stress; directly above the sand crests, are a series of mud volcanoes. Using 3-D seismic and pressure data we map the distribution of subsurface pressur...
متن کاملTexture Alignment in Simple Shear
We illustrate the flow behaviour of fluids with isotropic and anisotropic microstructure (internal length, layering with bending stiffness) by means of numerical simulations of silo discharge and flow alignment in simple shear. The Cosserat theory is used to provide an internal length in the constitutive model through bending stiffness to describe isotropic microstructure and this theory is cou...
متن کاملAnomalous Knudsen Diffusion in Simple Pore Models
1. Introduction Gas diffusion in mesoporous media is often in the Knudsen regime, cross sections of the pores being considerably smaller than the intrinsic molecular mean free path. Coppens [1] predicted the effect of fractal wall roughness on Knudsen self-diffusivity K D in a channel. A " trapping " process was identified as the cause of reduction of
متن کاملInstabilities in shear and simple shear deformations of gold crystals
We use the tight-binding potential and molecular mechanics simulations to study local and global instabilities in shear and simple shear deformations of three initially defectfree finite cubes of gold single crystal containing 3480, 7813, and 58,825 atoms. Displacements on all bounding surfaces are prescribed while studying simple shear deformations, but displacements on only two opposite surfa...
