    • An elastic plastic damage formulation for concrete: application to elementary and structural tests 

      Jason, L; Huerta, Antonio; Pijaudier-Cabot, Gilles; Ghavamian, S (2006-11)
      Article
      Open Access
      Pure elastic damage models or pure elastic plastic constitutive laws are not totally satisfactory to describe the behaviour of concrete. They indeed fail to reproduce the unloading slopes during cyclic loading which define ...
    • Arbitrary lagrangian-eulerian finite element analysis of strain localization in transient problems 

      Pijaudier-Cabot, Gilles; Bode, L; Huerta, Antonio (John Wiley & Sons, 1995-10)
      Article
      Open Access
      Non-local models guaranty that finite element computations on strain softening materials remain sound up to failure from a theoretical and computational viewpoint. The non-locality prevents strain localization with zero ...
    • Benchmarks for the validation of a non local model 

      Jason, L; Ghavamian, S; Pijaudier-Cabot, Gilles; Huerta, Antonio (2004-10)
      Article
      Restricted access - publisher's policy
      The aim of this contribution is to present a series of organised benchmarks that helps at validating the robustness of the FE implementation of a constitutive relation, its pertinence with respect to experiments, and ...
    • Discretization influence on regularization by two localization limiters 

      Huerta, Antonio; Pijaudier-Cabot, Gilles (1994-06)
      Article
      Open Access
      In materials with a strain-softening characteristic behavior, classical continuum mechanics favors uncontrolled strain localization in numerical analyses. Several methods have been proposed to regularize the problem. Two ...
    • 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
      Open Access
      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
      Restricted access - publisher's policy
      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 ...
    • Finite element analysis of bifurcation in nonlocal strain softening solids 

      Pijaudier-Cabot, Gilles; Huerta, Antonio (1991-09)
      Article
      Open Access
      Progressive damage in brittle heterogeneous materials produces at the macroscopic level strain softening from which theoretical difficulties arise (e.g. ill-posedness and multiple bifurcation points). This characteristics ...
    • Hydraulic behaviour of a representative structural volume for containment buildings 

      Jason, L; Pijaudier-Cabot, Gilles; Ghavamian, S; Huerta, Antonio (2007-07)
      Article
      Open Access
      For particular structures like containment buildings of nuclear power plants, the study of the hydraulic behaviour is of great concern. These structures are indeed the third barrier used to protect the environment in case ...
