Quantifying Shear-Induced Permeability Changes in Medium-Loose Sands
Publisher: ASCE
Abstract: For many applications in geotechnical engineering, an accurate assessment of soil hydraulic conductivity is important to predict settlements and pore water pressure changes. Laboratory test data can inform the permeability ...
Applying Network Modeling to Determine Seepage-Induced Forces on Soil Particles
Publisher: ASCE
Abstract: A pore network model (PNM) idealizes the pore space in a soil as voids (network nodes) connected by pore throats (network edges). Along each edge the fluid flow rate is linearly related to the pressure drop by a hydraulic ...
Effects of the Absence of Friction in Coarse-Grained Molecular Dynamics Simulations of Clay
Publisher: American Society of Civil Engineers
Abstract: Coarse-grained molecular dynamics (CGMD) simulations can advance the understanding of clay behavior. In CGMD simulations, the interactions between clay platelets are modeled and the data generated can be used to quantitatively ...
Exploiting DEM to Link Thermal Conduction and Elastic Stiffness in Granular Materials
Publisher: ASCE
Abstract: Estimating the effective thermal conductivity (ETC) of granular materials is important in various engineering disciplines. The ETC of a granular material is not unique, rather it depends upon the material’s packing ...
