An Improved Start for Coupled Consolidation Analysis
1988It is often convenient in engineering practice to idealize the loading of saturated soils into two stages: undrained loading daring which an increment of pore water pressure is developed but there is no flow of pore water, and dissipation during which the load applied to the soil remains constant and water flow occurs to dissipate the additional pore ...

A numerical study of coupled consolidation in unsaturated soils
Canadian Geotechnical Journal, 1998This paper first describes the numerical implementation of the coupled formulation for the theory of consolidation of unsaturated soils. The developed computer code is verified using the Mandel-Cryer problem and then is applied to the solution of coupled multidimensional consolidation problems.

3D Coupled Thermomechanical Finite Element Analysis of Ultrasonic Consolidation
Materials Science Forum, 2007A 3-D coupled temperature-displacement finite element analysis is performed to study an ultrasonic consolidation process. Results show that ultrasonic wave is effective in causing deformation in aluminum foils. Ultrasonic vibration leads to an oscillating stress field. The oscillation of stress in substrate lags behind the ultrasonic vibration by about

Coupled Consolidation and Contaminant Transport in Compressible Porous Media
International Journal of Geomechanics, 2011This paper presents an experimental and numerical investigation of coupled consolidation and contaminant transport in compressible porous media. Numerical simulations were performed using the CST2 computational model, in which a dual-Lagrangian framework is used to separately follow the motions of fluid and solid phases during consolidation.

Computational homogenization of coupled consolidation problems in micro‐heterogeneous porous media
International Journal for Numerical Methods in Engineering, 2011AbstractComputational homogenization is exploited for the analysis of transient hydro‐mechanically coupled problems subjected to quasistatic loading (consolidation) in micro‐heterogeneous porous solids. The classical approach of first‐order homogenization is adopted in the spatial domain on representative volume elements (RVE), which are introduced in ...

Civil-Comp Proceedings, 2010
In this paper we propose and describe a parallel implementation of a block preconditioner in the solution of saddle point linear systems arising from Finite Element (FE) discretization of 3D coupled consolidation problems. The inexact constraint preconditioner recently developed is combined with the parallel FSAI preconditioner which is used here to ...

Coupled filtration–consolidation model for vacuum-preloaded soft ground
GéotechniqueThe widespread utilisation of vacuum-assisted prefabricated vertical drains for managing clayey soft ground has led to the development of numerous consolidation models. However, these models have limitations when describing the filtration behaviour of soil under conditions of high water content, without the formation of a particle network.

Consolidation of Weakly Coupled Experimental System Modes
Normal modes of thin-walled axisymmetric shell structures are characterized by (1) overall body and (2) shell breathing families. By utilization of “body” deformation trial vectors, the two modal families are readily identified and separated. Local non-symmetrical structural features and/or imperfections cause body and breathing modes to mix (weak ...openaire +1 more source

Coupled Large Strain Consolidation and Solute Transport. I: Model Development
Journal of Geotechnical and Geoenvironmental Engineering, 2007The development of a numerical model, CST1, for coupled large strain consolidation and solute transport in saturated porous media is presented. The consolidation algorithm is one-dimensional and includes the capabilities of a previous code, CS2, with the addition of time-dependent loading, unload/reload effects, and an externally-applied hydraulic ...
