    • Topology Optimization Using the Constrained Natural Element Method 
      Communication avec acte
      CHEN, Yanda; ccMONTEIRO, Eric; ccKOUTIRI, Imade; ccFAVIER, Véronique (Association for Structural and Multidisciplinary Optimization in the UK (ASMO-UK), 2022-07)
      This paper focuses on a new topology optimization method for structures combining the solid isotropic material with penalization method (SIMP) and the constrained natural element method (CNEM). Common numerical instabilities ...
    • Aggregation-free fatigue constrained topology optimization using the constrained natural element method 
      Communication avec acte
      CHEN, Yanda; ccMONTEIRO, Eric; ccKOUTIRI, Imade; ccFAVIER, Véronique (Eccomas Proceedia/Institute of Structural Analysis and Antiseismic Research National Technical University of Athens, 2023-06)
      Fatigue resistance is one of the most important design criteria to ensure the safety of mechanical structures. In this paper, a topology optimization methodology for volume minimization under local fatigue constraints based ...
    • Fatigue-constrained topology optimization using the constrained natural element method 
      Article dans une revue avec comité de lecture
      CHEN, Yanda; ccMONTEIRO, Eric; ccKOUTIRI, Imade; ccFAVIER, Véronique (Elsevier BV, 2024-02)
      This research presents a topology optimization framework to achieve volume minimization with multi-axial high cycle fatigue criteria constraints by constrained natural element method. To solve the local minimization problem, ...
    • Investigation of the mechanical work during ultrasonic fatigue loading using pulsed time-resolved X-ray diffraction 
      Article dans une revue avec comité de lecture
      ccJACQUEMAIN, Vincent; CHEULEU, Christophe; ccRANC, Nicolas; ccCASTELNAU, Olivier; MICHEL, Vincent; VINCI, Doriana; MOCUTA, Cristian; THIAUDIERE, Dominique; ccFAVIER, Véronique (Crystallography Journals Online, 2024-01)
      In the energy production and transportation industries, numerous metallic structures may be subjected to at least several billions of cycles, i.e. loaded in the very high cycle fatigue domain (VHCF). Therefore, to design ...
    • Exact expressions of the uniaxial perfectly elasto-plastic stress wave and induced mechanical fields in the case of a finite impact: application to laser shock peening 
      Article dans une revue avec comité de lecture
      ccLAPOSTOLLE, Lucas; ccMORIN, Léo; ccDERRIEN, Katell; ccBERTHE, Laurent; ccCASTELNAU, Olivier (Cellule MathDoc/Centre Mersenne, 2023-12)
      This paper aims at providing exact expressions for the mechanical fields induced by Laser Shock Peening and comparing them to their numerical estimations. We use a uniaxial strain field hypothesis with an elastic perfectly ...
    • Enhancing weight perception in virtual reality: an analysis of kinematic features 
      Article dans une revue avec comité de lecture
      MOOSAVI, Mahdiyeh Sadat; RAIMBAUD, Pierre; ccGUILLET, Christophe; ccMERIENNE, Frédéric (Springer Science and Business Media LLC, 2024-03-08)
      This study investigates weight perception in virtual reality without kinesthetic feedback from the real world, by means of an illusory method called pseudo-haptic. This illusory model focuses on the dissociation of visual ...
    • NIR-hyperspectral camera analyses for differencing agroforestry and forestry poplar woods 
      Article dans une revue avec comité de lecture
      ccHEIM, Lucie; ccBRANCHERIAU, Loic; ccMARCHAL, Rémy; BOUTAHAR, Nabila; ccDENAUD, Louis; ccBADEL, Eric; ccMEGHAR, Karima (Springer Science and Business Media LLC, 2023-07-31)
      Wood characteristics of trees grown in agroforestry systems are still little studied, while their growth conditions are different from conventional stands. This work focused on the impact of the agroforestry system on the ...
