Flow liquefaction instability prediction using finite elements
Acta Geotechnica, 2014In this paper, a mathematical criterion based on bifurcation theory is developed to predict the onset of liquefaction instability in fully saturated porous media under static and dynamic loading conditions. The proposed liquefaction criterion is general and can be applied to any elastoplastic constitutive model. Since the liquefaction criterion is only

Wave-induced liquefaction and flow of subaqueous mud layers
Coastal Engineering, 1998Abstract In this paper, results of laboratory experiments on wave-induced liquefaction and transport of mud are presented. Wave-induced stresses inside the bed at the onset of liquefaction are shown to be just larger than the yield strength of the bed, which is determined independently with sounding tests.

Prediction of flow liquefaction instability of clean and silty sands
Acta Geotechnica, 2015Adding a small amount of non-plastic silt to clean sands may lead to dramatic loss of shear strength and a noteworthy tendency toward contraction when the mechanical behavior of the mixture is compared with that of the clean host sand. Thus, simulation of the behavior of silty sands with varying fines content is still a challenging subject in ...

An Entropy Flow Optimization Technique for Helium Liquefaction Cycles
1984Several potential applications of superconducting technology require large size refrigerators/liquefiers for cooling. The capital cost of such large size refrigerators is small compared with the operating cost. Therefore there is an emphatic need for highly efficient refrigerators.

Kinetics of donor-vehicle coal liquefaction in a flow reactor
Fuel, 1979Abstract Development of the Exxon Donor Solvent process has necessitated studies to more clearly define the influence of liquefaction conditions on coal conversion. Process studies were conducted in a 22.7 kg/day (fifty-pound-per-day) integrated pilot plant. Illinois No.

A methodology to evaluate the susceptibility of soils for liquefaction flow failures
2018An important factor in evaluating the stability of hydraulic fills against flow sliding is the undrained steady state strength mobilized in the field. This paper proposes an empirical relationship between three factors: the undrained strength back-calculated from fills which failed by flow sliding, equivalent clean sand normalized blow count values and
