Análisis geomecánico del deslizamiento del Forn de Canillo (Andorra) mediante el programa de elementos finitos Plaxis
(Universitat Politècnica de Catalunya, 2015-10)
Master thesis
Open AccessEl deslizamiento del Forn de Canillo (Principat d’Andorra) constituye uno de los más grandes deslizamientos del ámbito pirenaico. Forma un depósito de estructura compleja, debido a la superposición de depósitos que han ... -
Further developments in stress initialization in geomechanics via FEM and a two-step procedure involving Airy functions
(2017)
Conference report
Open AccessThe in-situ stress field in rock masses is a key aspect when a numerical analysis of a rock mass is carried out in any area of geo-engineering, such as civil, mining, or Oil & Gas. A method for the numerical generation of ... -
m-AGC tangent visco-plastic operator with hardening/softening, and application to the visco-plastic relaxation analysis of stable and unstable problems using fracture-based geomechanical interfaces
(2024-08)
Article
Open AccessA previous perfect visco-plastic constitutive formulation of the Perzyna type incorporating the concepts of prescribed stress increments and m-AGC tangent operator (m-Assumed algorithmic generalized compliance tangent ... -
Methods for FEM stress initialization based on stress functions, and application to a reservoir cross-section
(OnePetro, 2013)
Conference report
Restricted access - publisher's policyAn accurate description of the in-situ stress field in a rock mass is crucial in different areas of geo-engineering such as: underground excavations, hydrocarbon extraction, CO2 storage, hydraulic fracture etc. In this ... -
Revisión del deslizamiento de Canillo, Andorra

Visco-plasticity of zero-thickness interfaces with softening, and application to the study of fault reactivation
(Universitat Politècnica de Catalunya, 2023-02-10)
Doctoral thesis
Open Access(English) In the current context of both energy and environmental needs, there has been an increase in activities related to extraction and injection of fluids in the underground. It is known that a possible consequence ... -
Viscoplastic constitutive models for zero-thickness interface elements, formulation and applications
(2019)
Conference report
Open AccessAn energy-based work-softening visco-plastic model for zero-thickness interface elements has been developed as an extension of an existing elastic-perfectly-viscoplastic formulation. In the inviscid limit the model also ... -
