Effect of Anisotropic Yielding on the Flow Liquefaction of Loose Sand
Soils and Foundations, 2002 Abstract: In very loose sand, the ratio M-p of shear stress to mean normal stress at the peak point of the undrained effective stress path (UESP) is very close to the stress ratio M at the peak point of the capped yield surface. Stress ratios M-p can therefore be used in constructing yield surfaces of sands.

Unified analysis of liquefaction and the ground flow phenomenon [PDF]
International Applied Mechanics, 2007 Loose saturated sand behaves as a solid before liquefaction but as a fluid when the excess pore water pressure equals the initial confining stress, after which it recovers its strength. A simple constitutive equation for loose saturated sand was developed to express the phase transformation between a solid and fluid during liquefaction and the ground ...

Numerical characterization of under-expanded cryogenic hydrogen gas jets
AIP Advances, 2020 High-resolution direct numerical simulations are conducted for under-expanded cryogenic hydrogen gas jets to characterize the nearfield flow physics. The basic flow features and jet dynamics are analyzed in detail, revealing the existence of four stages ...

Seabed liquefaction around breakwater heads at a river mouth: An integrated 3D model
, 2021 In this paper, a 3D model is developed to investigate the foundation stability around breakwaters at a river mouth, where both ocean waves and river currents are considered. The present model consists of flow and seabed sub-models. In the flow sub-model,

The Combined Effect of Buoyancy and Excess Pore Pressure in Facilitating Soil Liquefaction [PDF]
, 2017 International audienceSoil liquefaction is a devastating earthquake hazard, commonly causing tilting, sinking and floating of infrastructure. The classical mechanism for liquefaction requires undrained and loosely packed soil, that upon shear experiences

Engineering geologic assessment of the slope movements and liquefaction failures of the 23 October 2011 Van earthquake (Mw= 7.2) [PDF]
Natural Hazards and Earth System Sciences, 2013 On 23 October 2011, a Mw = 7.2 earthquake occurred in the Van Province in eastern Turkey, killing 604 people. The earthquake was triggered by a thrust fault due to a compression stress in the region, and caused extensive damage over a large area.
