    • Effects of LCF Loadings on the HCF Life of Notched Specimens in Ferritic-Bainitic Steel 
      Article dans une revue avec comité de lecture
      BIDOUARD, Hadrien; ccPALIN-LUC, Thierry; ccSAINTIER, Nicolas; DUMAS, Christian; EL DSOKI, Chalid; KAUFMANN, Heinz; SONSINO, Cetin Morris (2009)
      Fatigue tests were performed on ferritic bainitic steel notched specimens (Kt = 2.5) under load controlled constant amplitude loading. These tests show that under constant amplitude tension compression loading, periodical ...
    • The behavior of statically-indeterminate structural members and frames with cracks present 
      Article dans une revue avec comité de lecture
      PARIS, Paul Croce; ccPALIN-LUC, Thierry (Elsevier, 2009)
      Crack stability is discussed as affected by their presence in statically-indeterminate beams, frames, rings, etc. loaded into the plastic range. The stability of a crack in a section, which has become plastic, is analyzed ...
    • Elastic–Plastic Transition in Iron: Structural and Thermodynamic Features 
      Article dans une revue avec comité de lecture
      PLEKHOV, O.A; NAIMARK, O.B; ccSAINTIER, Nicolas; ccPALIN-LUC, Thierry (MAIK Nauka/Interperiodica (МАИК Наука/Интерпериодика), 2009)
      The structural and thermodynamic features of the elastic–plastic transition in armco iron and its plastic deformation are studied. Energy storage in iron is shown to have a nonlinear character and be accompanied by wavelike ...
    • Scaling Invariance of Fatigue Crack Growth in Gigacycle Loading Regime 
      Article dans une revue avec comité de lecture
      OBORIN, V.; BANNIKOV, M.V.; NAIMARK, O.B; ccPALIN-LUC, Thierry (MAIK Nauka/Interperiodica (МАИК Наука/Интерпериодика), 2010)
      The role of the collective behavior of defect ensembles at the crack tip and the laws of fatigue crack propagation in R4 high strength steel have been studied under conditions of symmetric tension–compression gigacycle ...
    • Overload effects on a ferritic-baintic steel and a cast aluminium alloy: two very different behaviours 
      Article dans une revue avec comité de lecture
      ccSAINTIER, Nicolas; ccPALIN-LUC, Thierry; EL DSOKI, Chalid; BIDONARD, Hadrien; KAUFMANN, Heinz; DUMAS, Christian; VÖLLMECKE, F.J.; SONSINO, Cetin Morris (Wiley-VCH Verlag, 2011)
      Load controlled fatigue tests were performed up to 107 cycles on flat notched specimens (Kt =2.5) under constant amplitude and variable amplitude loadings with and without periodical overloads. Two materials are studied: ...
    • Comportement des matériaux cellulaires sous sollicitations dynamiques. Partie 2 : approche multi-échelles 
      Article dans une revue avec comité de lecture
      ccVIOT, Philippe (Elsevier, 2011)
      A multi scale methodology is proposed for the study of the cellular material behavior under dynamic loading. The behavior of polymeric foams studied depends on the constitutive material and the morphology of the porous ...
    • Three dimensional image correlation from X-Ray computed tomography of solid foam 
      Article dans une revue avec comité de lecture
      ROUX, Stéphane; HILD, François; BERNARD, Dominique; ccVIOT, Philippe (Elsevier, 2007)
      A new methodology is proposed to estimate 3D displacement fields from pairs of images obtained from X-Ray Computed Micro Tomography (XCMT). Contrary to local approaches, a global approach is followed herein that evaluates ...
