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 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 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 ... -
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 ...
