This PhD work deals with the understanding and the modelling of severe tribological contact. Severe tribological contact is observable in many applications such as manufacturing processes, such as cutting and forming processes. They are also present

International audience; Intermittencies are commonly observed in fluid mechanics, and particularly, in pipe flows. Initially observed by Reynolds (1883), it took one century for reaching a rather full understanding of this phenomenon whose irregular

Among the experiment results of the DynoTRAIN project, the measurement of Y and Q forces in different curves have been corrected and used to extract a representative friction coefficient, by comparison to a model using Kalker's approach. The result i
