Multiphysic approaches dedicated to metal forming processes:
 Two major scientific axes are developed in this subject. The first one concerns the better understanding of tool/lubricant/work piece interactions during forming. The second one focuses on the characterization of contact and friction conditions undergoing extreme loading, especially at high temperatures (up to 1200 °C). Both subjects aim to quantify the influences of phenomena acting at a mesoscopic scale on the whole process (macroscopic scale). They involve fluid/structure/thermal multi-physics coupling, and macroscopic - mesoscopic multiscale approaches. They allow to predict extreme surface behaviour and surface evolutions with time and loadings. Application fields are numerous: analyses of wear, of adhesion, effect of local strain resulting of the trapping of lubricant between surface asperities, lubrication defects caused by the growth of oxide scales at high temperature, prediction of surface damage (scratches, cracks).
Rheological and tribological behavior of surfaces at high temperature:
Previous studies have shown that coatings do not only modify the tribological behaviour of the surface, but also its rheological behaviour, even whith deposit in thin layers. It is therefore essential to characterize the bulk behaviour in the vicinity of the surface, including the coating and its substrate. A specific reverse methodology has then been developed to identify coating bulk behaviour. The methodology relies on innovative homogenisation procedures that do not distinguish the coating from the surface it lies on.
This method offers many advantages:
· the thickness of the coating has not to be measured to identify the bulk behaviour law,
· it implicitly takes into account the effect of diffusion, or the presence of organo and intermetallic compounds that may exist at the coating/substrate interface,
· the identified bulk behaviour law can be affected to a surface zone thicker than the coating alone. This peculiarity is very useful for finite element computations. Meshes do not have to be refined in order to present element size in surface of the same range of the coating thickness.
Regarding the tribological performances of surfaces, experimental friction tests have been designed to simulate thermo-mechanical conditions of contacts close to the industrial ones. Friction tests are adjustable in terms of contact pressure, plastic strain, sliding velocity, contactors and specimen temperatures. Contactors and specimens are machined from real tool and work-piece in order to present the same physical and chemical properties (bulk behaviour, roughness, chemical reactivity…). Methodologies were developed to identify test parameters adjustments, and to perform reliable and accurate data processing of the results (identification of coefficient of friction, of damage indicators, of lubricant efficiency…).
