A cross-anisotropic formulation for elasto-plastic models
Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (2016-06)
Article
Accés restringit per política de l'editorialA 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
Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (2017-05)
Article
Accés obertThe 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
Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (2017)
Text en actes de congrés
Accés obertStrain 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
Ruiz Restrepo, Daniel Felipe; Vaunat, Jean; Gens Solé, Antonio; Mánica Malcom, Miguel Ángel (American Society of Civil Engineers (ASCE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialThe 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 ... -
Geomechanics of shale repositories: mechanical behavior and modeling
Mánica Malcom, Miguel Ángel; Ruiz Restrepo, Daniel Felipe; Vaunat, Jean; Gens Solé, Antonio (John Wiley & sons, 2020)
Capítol de llibre
Accés restringit per política de l'editorialThis 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 analysis of expansive clays : constitutive and numerical modelling.
Ruiz Restrepo, Daniel Felipe (Universitat Politècnica de Catalunya, 2020-06-12)
Tesi
Accés obertBentonite-based materials are being currently considered in several countries as a backfill component in the multi-barrier concept for deep geological disposal of radioactive waste. The bentonite barrier fulfils several ... -

Text en actes de congrés
Accés restringit per política de l'editorialThe 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
Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (Universität Innsbruck, 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThe 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 ... -

Text en actes de congrés
Accés restringit per política de l'editorialThe 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 ... -
Thermo-mechanical analysis of the stability of a rock-cliff under climatic actions
Ruiz Restrepo, Daniel Felipe (Universitat Politècnica de Catalunya, 2013-01-10)
Projecte Final de Màster Oficial
Accés obert[ANGLÈS] This master thesis deals with the numerical analysis of the response of a rock cliff that presents recurrent instabilities as the results of the effect the climatic actions. Because the cliff is located above an ...
