    • Modélisation polycristalline du comportement d’un Alliage `a M´emoire de Forme (AMF) de type Ni-Ti sous sollicitations multiaxiales 
      Communication avec acte
      MAYNADIER, Anne; LAVERNHE-TAILLARD, Karine; HUBERT, Olivier; ccDEPRIESTER, Dorian (AFM, Maison de la Mécanique, 39/41 rue Louis Blanc, 92400 Courbevoie, France (FR), 2011)
      Les propriétés des AMF sont dues à une transformation de phase solide solide réversible induite par la contrainte ou la température. Pour les AMF de type Ni49,75%at-Ti, c’est une transformation isochore qui, d’une phase ...
    • Thermo-mechanical description of phase transformation in Ni-Ti Shape Memory Alloy 
      Communication avec acte
      MAYNADIER, Anne; LAVERNHE-TAILLARD, Karine; HUBERT, Olivier; ccDEPRIESTER, Dorian (Elsevier, 2011)
      The pseudo-elasticity of Shape Memory Alloys is due to a change in volumetric fraction between the high temperature phase (Austenite) and the low temperature phase (Martensite) under a mechanical loading. When a tensile ...
    • Fatigue Modelling for Gas Nitriding 
      Article dans une revue avec comité de lecture
      WEIL, Hadrien; ccJÉGOU, Sébastien; ccBARRALLIER, Laurent; COURLEUX, Alice; BECK, Guillaume (Università di Cassino, 2016)
      The present study aims to develop an algorithm able to predict the fatigue lifetime of nitrided steels. Linear multi-axial fatigue criteria are used to take into account the gradients of mechanical properties provided by ...
    • Modified WIC test : an efficient and effective tool for evaluating pipeline girth weldability 
      Article dans une revue avec comité de lecture
      KURJI, Rahim; GRIGGS, J.; GHOMASHCHI, R.; ccCONIGLIO, Nicolas (Maney Publishing, 2017)
      The Welding Institute of Canada (WIC) test is a simple and standardised weldability test for hydrogen assisted cold cracking that was developed in the 80s. It has been extensively utilised by the industry to qualify safe ...
    • A method to determine composite material residual tensile strength in the fibre direction as a function of the matrix damage state after fatigue loading 
      Article dans une revue avec comité de lecture
      CAOUS, Damien; ccBOIS, Christophe; ccWAHL, Jean-Christophe; ccPALIN-LUC, Thierry; VALETTTE, Julien (Elsevier, 2017)
      The phenomenon of residual strength in composite laminates after fatigue loading has been studied for decades but is generally expressed as a function of the number of cycles applied to the specimens. henomenological laws ...
    • Residual Stresses in Modelling Fatigue Lifetime of Gas Nitrided Iron-Based Alloys 
      Article dans une revue avec comité de lecture
      WEIL, Hadrien; COURLEUX, Alice; BECK, Guillaume; ccBARRALLIER, Laurent; ccJÉGOU, Sébastien (Materials Research Forum LLC, 2016)
      The objective of this work is to propose a model abled to optimize the mechanical properties from gaseous nitriding of steels (hardness, residual stresses) for a given loading and fatigue lifetime. Multiaxial fatigue ...
    • Will automated driving technologies obsolete today's effective restraint systems? 
      Article dans une revue avec comité de lecture
      SUBIT, Damien; VÉZIN, Philippe; ccSANDOZ, Baptiste; ccLAPORTE, Sébastien (American Public Health Association, 2017)
      Autonomous driving will trigger a shift in the epidemiology of road traffic injuries that is raising concerns for public health and requires the design of new strategies for the protection of vehicle occupants. Indeed, ...
