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 ... -
A simplified approach to account for directionality effects on 2D dynamic soil-structure interaction analysis
(CRC Press, 2019)
Conference report
Restricted access - publisher's policyIn this study, a simplified approach to account for directionality effects on twodimensional (2D) dynamic soil-structure interaction analyses (DSSI) is proposed. When an earthquake is recorded, the direction with the maximum ... -
A time-dependent anisotropic model for argillaceous rocks: application to an underground excavation in Callovo-Oxfordian claystone
(2017-05)
Article
Open AccessThe paper presents a constitutive model for argillaceous rocks, developed within the framework of elastoplasticity, that includes a number of features that are relevant for a satisfactory description of their hydromechanical ... -
Analysis of cone penetration in brittle liquefiable soils
(Elsevier, 2021-06)
Article
Restricted access - publisher's policyThe paper presents a comprehensive set of simulations of the cone penetration test with pore pressure measurements (CPTu test) in brittle, potentially liquefiable, soils using advanced numerical techniques. The large ... -
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 the hydration of an unsaturated seal
(American Society of Civil Engineers (ASCE), 2018)
Conference report
Restricted access - publisher's policyThe paper contains a coupled numerical analysis of the hydration of a potential sealing system for isolating shafts, ramps, and connecting galleries in a deep geological repository for high level nuclear waste. The modeling ... -
Analysis of underground excavations in argillaceous hard soils : weak rocks
(Universitat Politècnica de Catalunya, 2018-10-11)
Doctoral thesis
Open AccessMateriales arcillosos rígidos, que se encuentran en la zona de transición entre suelos duros y rocas blandas, están siendo considerados actualmente en varios países como la roca huésped para el almacenamiento geológico ... -
Geomechanics of shale repositories: mechanical behavior and modeling
(John Wiley & sons, 2020)
Part of book or chapter of book
Restricted access - publisher's policyThis chapter presents an overview of modeling frameworks available within the theory of elastoplasticity and able to capture main features of shale behavior including: yield under compression, failure under deviatoric ... -
Hydro-mechanical modelling of an unsaturated seal structure
(CRC Press, 2018)
Conference report
Restricted access - publisher's policyThe paper contains a coupled numerical analysis of the hydration of a potential sealing system for isolating shafts, ramps and connecting galleries in a deep geological repository for high level nuclear waste. The modelling ... -
Hydromechanical modelling of a tunnel excavated in argillaceous rock
(Universität Innsbruck, 2017)
Conference report
Restricted access - publisher's policyThe paper presents selected results from a hydromechanical analysis of an excavation at great depth in argillaceous rock. A constitutive model specifically developed for this type of materials has been used. It incorporates ... -
Modelling the mechanical behaviour of Callovo-Oxfordian argillite: formulation and application
(Springer, 2017)
Conference report
Restricted access - publisher's policyThe paper presents a constitutive model for argillaceous rocks, developed within the framework of elastoplasticity, that includes a number of features that are relevant for a satisfactory description of their hydromechanical ... -
Nonlocal plasticity modelling of strain localisation in stiff clays
(Elsevier, 2018-11)
Article
Open AccessThe paper addresses the numerical simulation of strain localisation in stiff clays that exhibit softening behaviour. An elastoplastic constitutive model developed to incorporate key features of stiff clay behaviour is ... -
Numerical simulation of the undrained stability of slopes in anisotropic fine-grained soils
(2019-01)
Article
Open AccessThe undrained stability of slopes in anisotropic fine-grained soils is studied in this paper using the finite element method (FEM). A constitutive model is presented, able to account for the observed variation of undrained ... -
Numerical simulation of underground excavations in an indurated clay using non-local regularisation. Part 1: formulation and base case
(2021-06)
Article
Restricted access - publisher's policyThe paper presents the numerical simulation of an underground excavation in the Callovo-Oxfordian argillaceous formation, performed in the Meuse/Haute-Marne underground research laboratory, within the context of deep ... -
Numerical simulation of underground excavations in an indurated clay using non-local regularisation. Part 2: Sensitivity analysis
(2021-09)
Article
Restricted access - publisher's policyA sensitivity study is presented to evaluate the influence of different parameters on the simulation of an underground excavation in the Callovo-Oxfordian (COx) argillaceous formation performed in the Meuse/Haute-Marne ...
