Recherche: 

I am interested in understanding the multiphysics behavior of materials in relationship with their microstructure.

 

  • Magnetorheological Elastomers (MREs)

MREs are soft composite materials made of an elastomer matrix filled with micron-sized magnetizable iron particles. They belong to the class of active materials since they can deform not only under mechanical loading but also when they are submitted to a magnetic field. My focus in this area is to develop experimental methods to characterize the coupled magneto-mechanical behavior of these soft active materials so as to provide relevant data for the validation of constitutive models developed in LMS by Nick Triantafyllidis and Kostas Danas [9, 14, C3, C5, P1]. In parallel, we also study interesting instability phenomena arising in MREs due to their microstructure or in structures made of MREs that are specially designed to create surface patterns [13].

 

 

 

 

  • Nanoarchitectured Sensors

On this topic, the goal is four-fold: design sensors; fabricate them via reproducible and cheap routes; characterize their performance in simulated environmental conditions; and understand the physical phenomena underlying their behavior and reliability. I am co-heading, with physicist Bérengère Lebental (IFSTTAR, LPICM) the "Smart Environment: Nanosensors and Nanoreliability Initiative", funded by the École polytechnique fund raising. This research relies on a unique experimental platform dedicated to nanosensors: PLATINE [12, 15, 16, C4, P2]. More details about our team and research can be found on the PLATINE website.

 

 

 

  • Polycrystalline Plasticity

Focus in this area was on developing full-field coupled techniques to perform energy balances at the scale of grains in FCC polycrystals in order to get a thermodynamics insight into the development of plasticity within the microstructure [1-3, 5, 7, 10, C1, C2]. Further work included investigating the relationship between grain orientation, the onset of plasticity and the localization patterns developing throughout the polycrystal [8, 11].
