Tribology and Materials Science


The research activity of the team of Tribology and Materials is devoted basically to the damage analysis of the materials subjected to the different deformation modes. The damage can occur at the centre of the pieces and in the frame of this context, our study is based on the plastic deformation, fracture and fatigue damage. Damage also can take place at the surface of the pieces. In this case, the study is based on the tribological aspect of the materials. Naturally, different types of solicitations can be considered including mechanical and/or thermal (in case of welding) and also chemical ones (environmental effect such as hydrogen gas).

Fatigue
This subject composes a transversal research activity of our research team. This phenomenon contains the accumulation of damage under the external action of dynamic stresses can both lead to the internal damage (fatigue at the centre of the pieces) and also to the surface damage (fatigue damage at the surface concerning the phenomena of fretting fatigue and/or micro chipping etc.). All the research activities carried out in this area entail both modelling and experimental study on the special devices developed in the LISMMA.
 
Microgeometry and Tribology
This research activity is essentially based on the Tribology but aims to evaluate the properties of the materials in favour of tribological capacity of a contact. General idea developed in the frame of this research is to understand tribological behaviour of the materials in case of a contact specifically on the surface of the pieces. One of these phenomena is the roughness characterized in microscale which makes discontinuous contact between two parts; it means that contact occurs only at certain points. This case is originally a specific behaviour of the materials under the service conditions that we are interested in. The other phenomena are related to the different nature of the materials present on the surface of pieces in comparison with that of the centre.
 
Damage of Materials
This research area is based on the internal damage analysis of the mechanical components subjected to severe loading conditions and related them the damage to the current structure at different scales. Different types of loading conditions are evaluated: pure mechanical–dynamic loading (i.e. impact and/or crash test applications), thermal (welding for example) and then physicochemical effects (environmental effect due to pressurized hydrogen gas) etc. This research area also comprises a component aimed to the development of new manufacturing processes (effectively based on the technique of powder metallurgy), designed for obtaining specific structures tailored to the resistance of the severe loading applications.
