Exposure and loss assessment of soil liquefaction in coastal area of Kulon Progo, Indonesia [PDF]
E3S Web of Conferences, 2020 Soil Liquefaction is a phenomenon of loss of strength of the granural soil layers due to increased pore water stress caused by earthquake shocks. Soil liquefaction can cause material and life damage if occurs in the developed area.

Hydrothermal processing of microalgae [PDF]
, 2013 Microalgae are regarded as a promising biomass resource for the production of biofuels and chemicals which does not compete with food production. Microalgae contain large amounts of lipids and have faster growth rates than terrestrial biomass. One of the

Flow Potential of Sand During Liquefaction
Soils and Foundations, 1998 In order to quantify the tendency to flow characteristics of sandy soils, the maximum value of excess pore water pressure ratio developed during undrained monotonic loading test was taken as an index property and defined as flow potential. Triaxial compression tests, triaxial extension tests and simple shear tests on Toyoura sand were conducted by ...

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 ...
