    • Estimation of crack opening from a two-dimensional continuum-based finite element computation 

      Dufour, F.; Legrain, Dominique; Pijaudier-Cabot, Gilles; Huerta, Antonio (2012-11)
      Article
      Accés obert
      Damage models are capable of representing crack initiation and mimicking crack propagation within a continuum framework. Thus, in principle, they do not describe crack openings. In durability analyses of concrete structures ...

    • Extraction of a crack opening from a continuous approach using regularized damage models 

      Dufour, F.; Pijaudier-Cabot, Gilles; Choinska, M; Huerta, Antonio (2008-11)
      Article
      Accés restringit per política de l'editorial
      Crack opening governs many transfer properties that play a pivotal role in durability analyses. Instead of trying to combine continuum and discrete models in computational analyses, it would be attractive to derive from ...

    • Numerical coupling between damage and gas permeability for concrete applied on a 3D splitting test 

      Ezzedine El Dandachy, M.; Briffaut, M.; Dufour, F.; Dal Pont, S. (CIMNE, 2015)
      Text en actes de congrés
      Accés obert
      Due to the industrial needs, one of the key issues nowadays is to develop numerical tools that are able to predict the leakage rate through a cracked structure. This paper presents a validation of a numerical modelling of ...

    • Stress based nonlocal interactions 

      Giry, C.; Dufour, F.; Mazars, J. (CIMNE, 2011)
      Text en actes de congrés
      Accés obert
      The progressive degradation of quasi-brittle materials can be reproduced efficiently by means of damage models. The presence of microcracks in the media gives a nonlocal aspect to the evolution of damage. By interacting with ...
