A constitutive model for partially saturated soils
(Institution of Civil Engineers (http://www.ice.org.uk/), 1990)
Article
Open AccessThe Paper presents a constitutive model for describing the stress-strain behaviour of partially saturated soils. The model is formulated within the framework of hardening plasticity using two imdependent sets of stress ... -
A cross-anisotropic formulation for elasto-plastic models
(2016-06)
Article
Restricted access - publisher's policyA cross-anisotropic formulation for elasto-plastic constitutive models based on a non-uniform scaling of the stress tensor is described. Taking advantage of the material symmetries characterising cross-anisotropy, only two ... -

(2009)
Conference report
Restricted access - confidentiality agreementIn this paper, a benchmark exercise from the DECOVALEX-2011 project is presented. Experimental results from a laboratory drying test in Opalinus Clay are used. First, the DECO- V ALEX project and the teams of the benchmark ... -
A hybrid multiphase model based on Lattice Boltzmann method direct simulation
(CIMNE, 2019)
Conference report
Open AccessBy means of the multicomponent Shan-Chen lattice Boltzmann method (LBM), we investigate the multiphase flow through porous media. Despite the excellent accuracy of the LBM, large domains result in unaffordable computational ... -
A multi-disciplinary approach to assess the impact of global climate change on infrastructure in cold regions
(2008)
Conference report
Open AccessImperial College London is researching with BP some potential impacts of future climate change. BP has a significant number of facilities in cold high-latitude regions, where global climate models predict significant rises ... -

Conference report
Restricted access - publisher's policyEste artículo muestra el potencial de los análisis retrospectivos como herramienta de control en problemas de Ingeniería Geotécnica y en particular en el control de precargas. La precarga es un método tradicional de mejora ... -
Analysis of a full scale in situ test simulating repository conditions
(Wiley, 1998)
Article
Open AccessCoupled thermo-hydro-mechanical (THM) analyses have been used to examine the interacting phenomena associated with the simultaneous heating and hydration of an engineered bentonite barrier placed in a drift excavated in ... -
Analysis of ground movements induced by diaphragm wall installation
(CRC Press, 2010)
Conference report
Restricted access - publisher's policyThe construction process of diaphragm walls can lead to movements in the surrounding area that are seldom taken into account. However, these movements may be important in situations where soft soils dominate. In this ... -
Analysis of strain localization with a non-local plasticity model
(2017)
Conference report
Open AccessStrain localization can be defined as the accumulation of deformations in narrow zones, in the form of shear bands or cracks, commonly observed in several geomaterials like concrete, rocks, dense sands, or stiff fine-grained ... -
Analysis of strain localization with a nonlocal plasticity model
(CIMNE, 2017)
Conference report
Open AccessIn the present paper a nonlocal plasticity model is described, intended to reproduce the mechanical behaviour of stiff fine-grained soils, including the objective simulation of strain localization; the phenomenon of accumulation ... -
