Geometrically and physically nonlinear coupled consolidation problem

PAMM, 2021
AbstractConsolidation is the process of soil compaction under load as water is squeezed out of a porous medium [1]. A physically and geometrically nonlinear formulation of the consolidation problem is developed. The developed nonlinear consolidation model is applied to simulate hyperelastic deformation of a biological material saturated with blood or ...

Coupled model of consolidation and creep for consolidation test

Journal of Central South University of Technology, 2008
For most soft soil, the consolidation process and the creep process were coupled and the character of settlement time curve was obtained by the consolidation test at the same time. A simple and continuous function was presented to express the whole process of consolidation including immediate settlement stage, the primary consolidation stage and the ...

Coupling energy efficiency and quality for consolidation of cloud workloads

Computer Networks, 2020
Abstract Efficient usage of IT equipment in Data Centers requires modulating their power-consumption according to the actual workload. The most effective strategy to this aim consists in consolidating as many applications as possible on the smallest number of servers, so that idle devices can be shut down or put in low-power states.

Coupled approach in simulation of soil consolidation

ce/papers, 2018
AbstractThe aim of this paper is to present a mathematical framework and its corresponding coupled finite element discretization for fully saturated porous media. The model is developed as a coupled displacement‐pressure formulation in which the porous medium is composed of a soil skeleton and water in the pores. The considered problem in this paper is

Coupling versus uncoupling in soil consolidation

International Journal for Numerical and Analytical Methods in Geomechanics, 1991
AbstractCoupling and uncoupling between the equilibrium and mass balance equations in soil consolidation problems in investigated in detail. A procedure for judging the strength of coupling is indicated. In the applications, particular emphasis is given to subsidence problems where the coupled nature of the problem is still sometimes questioned.

Model for Coupled CRS Consolidation and Contaminant Transport

Geoenvironmental Engineering, 2014
This paper describes the development of a numerical model, called CSTCRS1, for one-dimensional coupled contaminant transport and large strain consolidation under constant rate of strain (CRS) loading conditions. Numerical simulations using CSTCRS1 indicate that concentration boundary conditions can have an important effect on contaminant transport ...

An Improved Start for Coupled Consolidation Analysis

1988
It 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, 1998
This 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.

A fully coupled consolidation model of the subsidence of Venice

Water Resources Research, 1978
The subsidence of Venice, a well‐known historical town in Italy, is caused by the extensive withdrawal of groundwater in its industrial area, Marghera. A fully coupled finite element consolidation model is presented to simulate the subsidence and the piezometric decline in the considered area.
