    • Hardening effects on formability limit prediction based on Gurson-type damage models and bifurcation analysis 
      Communication avec acte
      ccCHALAL, Hocine; ccABED-MERAIM, Farid (CIMNE, 2017)
      In this work, ductility limits of metallic materials, associated with the occurrence of strain localization, are predicted using the GTN damage model coupled with bifurcation theory. The resulting approach is implemented ...
    • Structure-preserving neural networks 
      Article dans une revue avec comité de lecture
      HERNÁNDEZ, Quercus; BADÍAS, Alberto; GONZÁLEZ, David; ccCHINESTA SORIA, Francisco; ccCUETO, Elias (Elsevier, 2021)
      We develop a method to learn physical systems from data that employs feedforward neural networks and whose predictions comply with the first and second principles of thermodynamics. The method employs a minimum amount of ...
    • Multiphoton imaging and Raman spectroscopy of the bovine vertebral endplate 
      Article dans une revue avec comité de lecture
      CRAWFORD-MANNING, Fay; VARDAKI, Martha Z.; GREEN, Ellen; MEAKIN, Judith R.; ccVERGARI, Claudio; STONE, Nick; WINLOVE, C. Peter (Royal Society of Chemistry (RSC), 2021)
      The interface between the intervertebral disc and the vertebral body is important to the discs’ biomechanics and physiology, and is widely implicated in its pathology. This study aimed to explore biochemically and structurally ...
    • Martensite Transformation and Superelasticity at High Temperature of (TiHfZr)74(NbTa)26 High-Entropy Shape Memory Alloy 
      Article dans une revue avec comité de lecture
      PELTIER, Laurent; ccBERVEILLER, Sophie; ccMERAGHNI, Fodil; LOHMULLER, Paul; LAHEURTE, Pascal (Springer Science and Business Media LLC, 2021)
      In this work, a (TiHfZr)(NbTa) 26 (%at) high-entropy quinary alloy has been developed especially for high-temperature superelastic applications and studied over a large range of temperatures. The mechanical properties of ...
    • Determination of forming limit diagrams based on ductile damage models and necking criteria 
      Communication avec acte
      ccCHALAL, Hocine; ccABED-MERAIM, Farid (ACEX, 2016)
      In this paper, forming limit diagrams (FLDs) for an aluminum alloy are predicted through numerical simulations using various localized necking criteria. A comparative study is conducted for the FLDs determined by using the ...
    • Seismic vulnerability assessment of buried pipelines: A 3D parametric study 
      Article dans une revue avec comité de lecture
      GERMOSO, Claudia; GONZALEZ, Omar; ccCHINESTA SORIA, Francisco (Elsevier BV, 2021)
      Pipeline structural analysis is a well-developed topic in engineering and research practice. Since water, oil or gas pipeline systems are a key part of modern development, therefore, it is important to ensure an appropriate ...
    • CT-based semi-automatic quantification of vertebral fracture restoration 
      Article dans une revue avec comité de lecture
      LE PENNEC, Gilles; CAMPANA, Sophie; JOLIVET, Erwan; VITAL, Jean-Marc; BARREAU, Xavier; ccSKALLI, Wafa (Informa UK Limited, 2012)
      Minimally invasive surgeries aiming to restore fractured vertebral body are increasing; therefore, our goals were to create a 3D vertebra reconstruction process and design clinical indices to assess the vertebral restoration ...
