    • Physical aging and its effect on mechanical properties of toughened PLA films 
      Communication sans acte
      RUELLAN, Alexandre; ANDRE, Jérémy; SAELICES JIMENEZ, Lidia; GUINAULT, Alain; DUCRUET, Violette; DOMENEK, Sandra; ccSOLLOGOUB, Cyrille (2023-05)
      Physical aging plays an important role in determining the long terms performance of polymers, especially PLA, whose Tg is close to ambient temperature. Considering long term performances, PLA/PHBV/PODC blends are the ...
    • AI-based Text Generation for Semantic Search Robustness : Application to Defence 
      Communication avec acte
      FENDZI, Claude; CARRON, Bruno; GADEK, Guillaume (IEEE, 2023-11)
      One of the biggest challenges in successfully applying Artificial Intelligence (AI) in the Defense sector is the availability of trustful domain specific data to train AI models on. These data have to be generated and ...
    • Smart actuators based on electroactive fluorinated polymers: relationship between molecular organization and electroactive response 
      Communication avec acte
      ZANCHI, Sara; ccROLAND, Sébastien; LE GOFF, Lena; ccTHUAU, Damien; MARGERIT, Pierre; ccRÉBILLAT, Marc; ccILIOPOULOS, Ilias; ccTENCÉ-GIRAULT, Sylvie (Eccomas proceedia/Dept. of Mechanical Engineering & Aeronautics University of Patras, 2023-07)
      Electroactive polymers (EAP) show a change of properties (size, shape, temperature…) when an electric field is applied. Poly(vinylidene fluoride-ter-trifluoroethylene-ter-chlorotrifluoroethylene) P(VDF-ter-TrFE-ter-CTFE) ...
    • 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; ccVINCI, Doriana; ccFAVIER, Véronique; MOCUTA, Cristian; THIAUDIERE, Dominique (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 ...
