The aim of this PHD is, firstly, to elaborate the MC powder by mechanosynthesis and the composite by mixing the powder with a thermoplastic polymer and, secondly, to characterize them in order to identify the effects of elaboration process and the parameters of the constitutive laws. Finally, numerical simulations of the magnetocaloric effect and the elastocaloric one will be performed on simple geometries in order to qualify the efficiency of each of these two cooling strategies.

The Applied Mechanics Department of the Femto-ST Institute, located in Besançon, is looking for an electronics engineer for a 24-month fixed-term contract (renewable once under conditions).

The person is recruited, for a 24-month fixed-term contract (renewable once under conditions) within the framework of a program ERDF Project - Franche-Comté and Jurass massif including two partners FEMTO-ST for the University Franche -Comté and SilMach SA as an industrial leader of the project.

Profile sought and some key skills:

In the frame of a large European Project which aims at developing advanced bio-based composites, the main objective of the internship will be to estimate the structural dynamics properties of hifi components that includes flax fibers-based components

The internship will take place in FEMTO-ST, Department of Applied Mechanics, in close collaboration with the firm « Wilson Benesch » which is one of the world leaders on carbon fibers-based high end speakers

Metal nitrides of titanium and aluminum (TiAl) N are coatings used since many years for their outstanding properties of hardness and resistance to oxidation [1]. To further improve the mechanical performances, we are currently exploring the use of cyclic control signal reactive sputtering (RGPP), a process patented in 2006 [[4].
