Welcome to this website, which summarises my research activities (Civil and Mechanical Engineering Laboratory – LGCGM – EA3913) at the Institut National des Sciences Appliquées (INSA) in Rennes (France).
Areas of expertise
- Identification of the rheological behaviour of metallic materials under different conditions: large deformation, high temperatures, high strain rates, complex loading paths, etc.
- Prediction and characterisation of the formability of metal sheets, including the effect of strain path, temperature and strain rate
- Development of specific experimental procedures on a in-plane biaxial traction device
- Numerical simulation of forming processes: incremental forming, hydroforming, etc.
- Instabilities and scale effects in sandwich structures
