  Damage Assessment of Polyamide-Based Woven Composites Using Multi-Directional Lamb Waves After Fatigue or Impact Loading 

  Article dans une revue avec comité de lecture

  MIQOI, Nada; POMAREDE, Pascal; MERAGHNI, Fodil; DECLERCQ, Nico; DELALANDE, Stéphane (2025-05)

  This study presents a novel experimental methodology designed to assess damage in woven glass fibers reinforced polyamide 6,6/6 composites, specifically subjected to low-velocity impact and cyclic tensile loading. Conventional ...

  Hierarchical micromechanical modeling for CNT-coated fuzzy fiber composites accounting for viscoplasticity and interfacial damage 

  Article dans une revue avec comité de lecture

  HANOUN, Ibtissam; CHATZIGEORGIOU, George; MERAGHNI, Fodil (Elsevier BV, 2025-05)

  This study investigates fuzzy fiber composites, characterized by a viscoplastic matrix and fuzzy fibers, i.e. fibers coated with radially aligned carbon nanotubes (CNTs). A comprehensive micromechanical framework is developed ...

  Dynamic Behaviors of Couple Stress Quadrilateral Thick Microplates within a Refined DQFE Framework 

  Article dans une revue avec comité de lecture

  PENG, Zihao; ZHANG, Bo; JEBAHI, Mohamed; WEN, Pengjun; LI, Cheng; ZHANG, Xu (World Scientific Pub Co Pte Ltd, 2025-03)

  This study proposes a novel refined differential quadrature finite element (DQFE) framework for the size-dependent dynamic analysis of thick quadrilateral microplates, incorporating couple-stress effect and two kinematic ...

  Multiscale Thermodynamics-Informed Neural Networks (MuTINN) for nonlinear structural computations of recycled thermoplastic composites 

  Article dans une revue avec comité de lecture

  SEKKAL, S.E.; EL FALLAKI IDRISSI, Mohammed; MERAGHNI, Fodil; CHATZIGEORGIOU, George; CHINESTA SORIA, Francisco (Elsevier BV, 2025-04)

  Fiber-reinforced thermoplastic composites are increasingly valued for their light-weight properties, mechanical performance, and recyclability, yet the recycling process introduces microstructural heterogeneities that ...

  Investigation of non-Schmid effects in dual-phase steels using a dislocation density-based crystal plasticity model 

  Article dans une revue avec comité de lecture

  ZHU, Jianchang; BEN BETTAIEB, Mohamed; LI, Zhenhuan; ABED-MERAIM, Farid; HUANG, Minsheng (Springer Science and Business Media LLC, 2025-03)

  Non-Schmid (NS) effects in body-centered cubic (BCC) single-phase metals have received special attention in recent years. However, a deep understanding of these effects in the BCC phase of dual-phase (DP) steels has not ...
