Isabelle BRUANT
She is the coordinator of the FunGPT project. She completed her PhD at the École Normale Supérieure de Cachan, defending her thesis in 1999 on the optimisation of piezoelectric actuator and sensor networks for active vibration control. She has been an Associate Professor at Paris Nanterre University since 2001 and has held her Habilitation to Direct Research (HDR) in 2016. Since 2019, she has served as the head of the Functional Materials Group, a cross-disciplinary research team she established at the LEME laboratory.
For over a decade, her research at LEME has focused on the active vibration control of Functionally Graded Materials (FGM) and Functionally Graded Piezoelectric Materials (FGPM). Her expertise primarily covers the numerical modeling of composite structures based on piezoelectric materials, as well as the optimization of transducer networks, sensing, and control systems. She initiated the collaboration with the project partners in 2021, leading to significant work on the development and characterization of Nickel and BaTiO3-based FGMs.
As well as beeing the coordinator of FunGPT project, she is the leader of the WP3 related to the developement of a predictive numerical tool for FGPM efficiency.
Jihed ZGHAL
He holds a PhD in Mechanics and Materials, which he obtained in 2016 from ENSAM. Since 2020, he has been an Associate Professor in the Mechanical and Production Engineering (GMP) department at the IUT of Ville-d’Avray, Paris Nanterre University. As a researcher in mechanics, he is a member of the LEME laboratory, within the Mechanics cluster and the Functional Materials Group.
His research focuses on mechanics and materials, with a particular interest in structural behavior modeling, damage, and cracking. He actively contributes to the scientific advancement of his field through his publications and the supervision of doctoral research.
In the FunGPT project, he is involved in the WP2 related to the mechanical characterization of the FGPM and in the WP3 related to the developement of the predictive numerical tool for FGPM damage behavior.
Johann PETIT
He is an Associate Professor at Paris Nanterre University. He completed his PhD thesis in 2010 at UTT – LASMIS (Troyes) on the following topic: elasto-plastic behavior and strain localization – multiscale analysis using ESPI and acoustic emission. His research activities fall within the field of mechanics of materials, focusing primarily on the characterization of the mechanical properties and behavior of metallic materials under quasi-static (tensile) and fatigue loading. Specifically, he studies macroscopic strain localization phenomena in tension (necking, Lüders bands, PLC) and the mechanisms of fatigue crack initiation and propagation in the Very High Cycle Fatigue (VHCF) regime. Regarding the latter, he also works on the development of ultrasonic fatigue testing machines and test instrumentation.
To monitor these tests, he utilizes laser interferometry, digital image correlation (DIC), infrared thermography, and acoustic emission; these techniques are sometimes coupled for enhanced analysis.
In the FunGPT project, he is involved in the WP2 related to the thermal and mechanical characterization of the FGPM.
Julie CEDELLE
She is an Associate Professor in Process Engineering and Energy Systems. Her research focuses on the processing, characterization, and optimization of materials and processes for energy-related applications. Throughout her career, she has conducted research in the fields of plasma-sprayed ceramic coatings, material sintering, thermal and radiative metrology, and functionally graded materials. Her work is based on an experimental approach combining material processing, multiscale characterization, and heat transfer analysis. More recently, her research has focused on ceramic/metal functionally graded materials for energy harvesting, vibration control, and piezoelectric device applications. In the FunGPT project, she is involved in the WP2 related to the thermal characterization of the FGPM.
Abdelmalek BARKI
He is currently completing a PhD in Damage Mechanics at LEME, where he develops diffuse-field damage models based on phase-field and lip-field approaches. His background combines finite element modeling, multiphysics simulation and damage mechanics. He has previously worked on the modeling of energy harvesters based on Functionally Graded Piezoelectric Materials. During his PhD, he developed numerical phase-field tools in FEniCS for the prediction of damage in quasi-static and dynamic settings. In the FunGPT project, he will be involved in the development of numerical models for lead-free FGPM transducers dedicated to active vibration control. His work will focus on the modeling of thermo-piezoelectric coupling, damage simulation, and the assessment of how damage affects the efficiency of FGPM transducers.
