The MoSES group

MoSES = Modeling Simulation and Experiment Synergy

The MoSES group strives at (i) developing the synergy between mathematically rigorous multi-scale theoretical models, their transformation into efficient numerical tools to run simulations, and advanced experimental approaches, in order to thoroughly understand the multi-scale behavior of structural materials, specifically metals and alloys, and (ii) using the knowledge gained to engineer material microstructure with desired properties.

The MoSES group is part of the Solid Mechanics Laboratory (LMS), a mixed research unit (UMR 7649) between the Centre National de la Recherche Scientifique (CNRS) and the Ecole Polytechnique, France.

Group Leader: Manas V. Upadhyay

PhD students

Mohanan, Nikhil ↗

Nikhil started his PhD at the Ecole Polytechnique on September 1, 2020. He has obtained his bachelor degree in Mechanical Engineering in 2015 from the Mahatma Gandhi University (Kottayam, India), followed by his Master of Science diploma in Mechanics and Mathematical Modeling in 2020 from the Peter the Great St. Petersburg Polytechnic University (Russian Federation). His doctoral research is focused on creating a model to understand the role of intrinsic heat treatment on microstructure evolution during metal additive manufacturing.

Abdesselam, Kouider Abdellah ↗

Abdellah started his PhD at the Ecole Polytechnique on September 1, 2021. He has obtained his Master’s degree in Material Science from Polytech Grenoble, Grenoble Alpes Universty. His doctoral thesis, funded by the ERC Starting Grant 2020 project GAMMA (# 946959), focuses on performing in-situ synchrotron X-ray diffraction and radiography experiments to study the microstructural evolution of technologically important alloys during additive manufacturing.

Lima Chaves, Gabriel Dante ↗

Gabriel started his PhD at the Ecole Polytechnique on October 1, 2021. Originally from Brazil, he did his engineering studies at SIGMA Clermont and graduated in September 2020. His doctoral thesis, funded by the ERC Starting Grant 2020 project GAMMA (# 946959), focuses on performing thermo-mechanical simulations to study dislocation dynamics in order to study the microstructural evolution of technologically important alloys during additive manufacturing.

Post-doctoral researchers

Gaudez, Steve ↗

Steve holds a Master’s degree in Metallurgy obtained at Université de Lorraine. During his master’s thesis project, he investigated the quenching and partitioning process (Q&P) via in-situ high energy X-ray diffraction experiments (ANR “CAPNANO” project). During his PhD thesis at the Institut Jean Lamour (Nancy, France) in the Microstructures et Contraintes team, he studied the microstructural evolution, including secondary hardening precipitation, during the tempering of martensite and nano-bainitic microstructures in a RFCS “STEELSECO” project. He is specialized in solid phase transformations (characterization and mechanisms) and synchrotron experiments. His publications can be found here.

Santos Macias, Juan Guillermo ↗

Juan Guillermo Santos Macías holds a PhD in engineering science and technology (Project entitled ‘‘Laser powder bed fusion AlSi10Mg damage and fatigue resistance improvement by post-processing’’) from the institute of mechanics, materials and civil engineering at UCLouvain (Belgium). His interests revolve around the study of microstructure and mechanical behaviour of materials and their interrelationship. In particular, he has studied in detail the damage and fatigue performance of additive manufactured aluminium alloys, notably making use of synchrotron X-ray tomography for these purposes. He completed civil engineering studies with a specialisation in materials at the Universidad Carlos III de Madrid (Spain) and carried out his master thesis (Entitled ‘‘Influence of the grain size and phase content on the mechanical behaviour of magnesium alloys. Gravity casting and SPS manufactured’’) at KULeuven (Belgium).
