Dr. Mohamed JEBAHI is working in the field of multi-scale modeling of the mechanical behavior of materials. During his PhD, he worked on the coupling between discrete (small-scale) and continuum (large-scale) approaches. Then, he focused on the modeling of small-scale effects using strain gradient (crystal) plasticity theories. Throughout the present project, he strives to provide an enhanced understanding of small-scale plasticity in relation with these theories.

Dr. Samuel FOREST is working in the field of continuum modelling of the mechanical behavior of materials of structures. His work aims at introducing the physical aspects of deformation and fracture of materials into the framework of continuum mechanical modeling. He has actively participated in the recent developments of the mechanics of generalized continua, including strain gradient and micromorphic media. Since 2022, he is member of the Académie de Science, Sciences Mécaniques et Informatiques.

Dr Marc FIVEL is working in the field of multi-scale modeling of crystal plasticity. His main activity concerns discrete dislocation dynamics simulations with boundary conditions enforced by Finite Element calculations (see http://www.numodis.com). Recently he has been involved in modeling of material damage due to cavitation erosion in hydrodynamics devices such as turbines, pumps or propellers.

Dr. Jean-Sébastien LECOMTE is a CNRS Research Engineer specialized in material science.  His main activity concerns defects and deformation modes of hexagonal materials (Zn, Ti, Mg). He has a rare know-how applied to the characterization of small-scale structure materials (SEM, TEM, EBSD, EDX, Nano-indentation, Ultra-nano-indentation, AFM, etc.). He is responsible for the LEM3’s nanoindentation and electron microscopy platforms. 

Dr. Christophe SCHUMAN is an associate Professor (HDR) at Lorraine University since 1998. He belongs to LEM3, IMPACTS department, since 2000. His research topic is the deformation mechanisms in HCP in relation with texture-microstructure-properties. He works on titanium alloy since 2002. He has more than 20 publications on HCP and has a large interaction with industrial partners such as Airbus, Specitubes, Aubert & Duval, Valeo (Al).
