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
Accés obertPure 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
Accés obertNon-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
Accés restringit per política de l'editorialThe 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
Accés obertIn 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
Accés obertDamage 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'editorialCrack 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
Accés obertProgressive 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
Accés obertFor 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 ...
