A FIC-based stabilized mixed finite element method with equal order interpolation for solid–pore fluid interaction problems
(2017-01)
Article
Open AccessA new mixed displacement-pressure element for solving solid–pore fluid interaction problems is presented. In the resulting coupled system of equations, the balance of momentum equation remains unaltered, while the mass ... -
An isotropic damage model for geomaterials in the KRATOS framework
(Universitat Politècnica de Catalunya, 2015-02)
Master thesis
Open AccessL’evolució de la fractura en materials quasi-fràgils com el formigó, les roques, o els sòls, sovint és tractada amb estovament de deformacions dins el marc de la mecànica del dany continu. Aquestes relacions constitutives ... -
An isotropic damage model for geomaterials in the Kratos framework
(Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2015)
Book
Open AccessProgressive fracture in quasi-brittle materials such as concrete, rocks, soils, is often treated as strain softening in continuum damage mechanics. Such constitutive relations favour spurious strain localization and ... -
Combination of a non-local damage model for quasi-brittle materials with a mesh-adaptive finite element technique
(2016-05)
Article
Open AccessProgressive fracture in quasi-brittle materials is often treated via strain softening models in continuum damage mechanics. Such constitutive relations favour spurious strain localization and ill-posedness of boundary value ... -
Development of new computational methods for fluid-structure interaction analysis of multi-fractured media
(Universitat Politècnica de Catalunya, 2018-01-25)
Doctoral thesis
Open AccessThe objective of this thesis is the derivation and implementation of a robust Finite Element formulation for the solution of solid-pore fluid coupled problems in multi-fractured porous media. A coupled displacement-pore ... -
Finite element modelling of fracture propagation in saturated media using quasi-zero-thickness interface elements
(Elsevier, 2018-04)
Article
Restricted access - publisher's policyA new computational technique for the simulation of 2D and 3D fracture propagation processes in saturated porous media is presented. A non-local damage model is conveniently used in conjunction with interface elements to ...
