Presentation

Professor of solid mechanics at ENSTA/IP Paris, I am interested in crack patterns in the context of the mechanics/physics of brittle fracture. I combine mechanics and physics, experimental and numerical simulations to understand and predict when and how cracks propagate. I develop and test models that enable to finely quantify (i) certain complex, three-dimensional aspects of crack geometry and (ii) their impact on fracture toughness. The challenges range from ensuring the reliability of sensitive components (nuclear, aeronautical, etc.) to reducing their carbon footprint.
