Reseach Activities

My research focuses on the study and modeling of multiphysics coupling and particularly electro-magneto-thermo-mechanical couplings. The problem is addressed both in terms of experimental characterization and modeling. This work aims to better understand the physical mechanisms involved in the coupling phenomena in order to propose a suitable modeling.

In general, this research applies to materials for sensors and actuators. They mainly concern the so-called active materials (piezoelectric, giant magnetostrictive materials...), which exploit properties of multiphysics coupling for converting an initial signal (eg a magnetic field) into a signal of a different physical nature (eg a deformation). The ultimate goal of these studies is to provide laws adapted to numerical computing (like finite elements method) for the design of devices based on smart materials.
