Benoît Lé graduated with a M. Sc. in computational Mechanics and a PhD from Ecole Centrale de Nantes, France. His PhD works was about modelling reinforced concrete, using the eXtended Finite Element method (X-FEM) for the steel reinforcements, and the Thick Level Set approach to fracture (TLS) for the concrete. He is now a research engineer at the Ecole Centrale de Nantes. His works focus on damage and fracture mechanics. In particular, he is involved in the implementation of the TLS in the finite element code eXlibris, developped at the Research Institute of Civil Engineering and Mechanics (GeM).
