RISBidirectional Shear Wave Velocity Measurements to Track Fabric Anisotropy Evolution of a Crushed Silica Sand during Shearing
Publisher: ASCE
Abstract: Continuous bidirectional shear wave velocity measurements were performed in the vertical (V) and horizontal (H) directions to characterize fabric evolution of triaxial soil specimens during shear, wherein, in addition to ...
Prediction of Undrained Behavior of Isotropically and Anisotropically Consolidated Firoozkuh Sand: Instability and Flow Liquefaction
Publisher: American Society of Civil Engineers
Abstract: Recent experimental findings highlight the impact of anisotropic consolidation on triggering flow liquefaction failures. Results of a series of undrained tests on isotropic and anisotropic consolidated Firoozkuh sand are ...
Instability of Particulate Assemblies under Constant Shear Drained Stress Path: DEM Approach
Publisher: American Society of Civil Engineers
Abstract: The discrete element method (DEM) is applied to investigate instability of frictional particulate assemblies sheared under the triaxial constant shear drained (CSD) condition. The instability in loose samples occurs in the ...
Stress-Displacement Response of Sand–Geosynthetic Interfaces under Different Volume Change Boundary Conditions
Publisher: ASCE
Abstract: Volume change boundary conditions might dictate significant changes in normal stress and, accordingly, dramatically affect the stress-displacement response of soil-structure interfaces. Using a Norwegian Geotechnical ...
