A continuous-discontinous model for softening and cracking based on non-local displacements
(2008)
Conference report
Open AccessA continuous-discontinuous model to simulate numerically an entire failure process is presented. Crack inception and its propagation is modelled by means of a gradient non-local model based on non-local displacements. To ... -
A continuous-discontinuous model for crack branching
(John Wiley & sons, 2019-10-05)
Article
Open AccessA new continuous-discontinuous model for fracture that accounts for crack branching in a natural manner is presented. It combines a gradient-enhanced damage model based on nonlocal displacements to describe diffuse cracks ... -
A finite element strategy coupling a gradient-enhanced damage model and cohesive cracks for quasi-brittle materials
(2013)
Conference report
Restricted access - publisher's policyA new combined strategy to describe failure of quasi-brittle materials is presented thus allowing the complete description of the process, from initiation of damage to crack propagation. For the early stages of the process, ... -
A finite element strategy coupling a gradient-enhanced damage model and cohesive cracks for quasi-brittle materials
(CIMNE, 2013)
Conference report
Open AccessA new combined strategy to describe failure of quasi-brittle materials is presented thus allowing the complete description of the process, from initiation of damage to crack propagation. For the early stages of the process, ... -
A general framework for softening regularisation based on gradient elasticity
(2011-05-01)
Article
Open AccessA general non-local approach to regularise strain-softening continua is presented. The key idea is to introduce the gradient-type enrichment at the level of displacements (rather than some internal variable), so the model ... -
A geometric bridge between regularised damage and energetically equivalent cracks
(2012)
Conference report
Open AccessIn order to achieve a better characterisation of a whole failure process, models which combine damage and fracture mechanics have recently been proposed. Here, a new combined methodology is presented: in order to describe ... -
A medial-axis-based model for propagating cracks in a regularised bulk
(John Wiley & Sons, 2015-02-17)
Article
Open AccessA new continuous-discontinuous strategy for the simulation of failure is presented. The continuous bulk is regularised by means of a gradient-enhanced damage model, where non-locality is introduced at the level of ... -
A new continuous-discontinuous damage model: cohesive cracks via an accurate energy-transfer process
(2014-02)
Article
Open AccessA new continuous-discontinuous strategy to describe failure of quasi-brittle materials is presented. For the early stages of the failure process, a gradient-enhanced model based on smoothed displacements is employed. As ... -
Condiciones de contorno en modelos de gradiente con desplazamientos suavizados
(2012)
Article
Open AccessLos modelos de gradiente basados en desplazamientos suavizados son una alternativa a los modelos estándares para simular numéricamente el proceso de fallo de materiales. En esta formulación alternativa coexisten los ... -

Continuous-discontinuous modelling for quasi-brittle failure: propagating cracks in a regularised bulk
(Universitat Politècnica de Catalunya, 2013-12-05)
Doctoral thesis
Open AccessA new strategy to describe failure of quasi-brittle materials -concrete, for example- is presented. Traditionally, numerical simulation of quasi-brittle failure has been tackled from two different points of view: damage ... -
Continuous-discontinuous models of failure based on non-local displacements
(Universitat Politècnica de Catalunya, 2009-01)
Master thesis
Open AccessIn this work, a new continuous-discontinuous approach is presented. This new technique is based on a non-local model (such as continuum damage or plasticity) based on non- local displacements. On the one hand, this work ... -
Discontinuous failure in a gradient-enhanced continuous damage model: a regularised displacement framework
(CIMNE, 2011)
Conference report
Open AccessTo simulate numerically a failure process, a new kind of model which combines the two traditional approaches (damage and fracture mechanics) has been proposed in the literature. The basic idea of these hybrid strategies ... -
Modelling advective gas flow in compact bentonite: lessons learnt from different numerical approaches
(Elsevier, 2021-03)
Article
Open AccessIn a repository for radioactive waste hosted in a clay formation, hydrogen and other gases may be generated due to the corrosion of metallic materials under anoxic conditions, the radioactive decay of waste and the ...
