[en] This paper presents a numerical investigation of microscopic lubricant flows from the cavities to the plateaus
of the surface roughness of metal sheets during forming processes. This phenomenon, called micro-plastohydrodynamic
lubrication, was observed experimentally in various situations such as compression sliding
tests, strip drawing and cold rolling. It leads to local friction drop and wear reduction. It is therefore critical to
achieve a good understanding of this phenomenon. As to move towards that goal, a multiscale fluid–structure
interaction model is developed to model lubricant flows at the microscopic scale. These simulations are
made possible through the use of the Arbitrary Lagrangian Eulerian (ALE) formalism. In this paper, this
methodology is used to study plane strip drawing. The numerical model is able to predict the onset of lubricant
escape and the amount of lubricant flowing on the plateaus. Numerical results exhibit good agreement with
experimental measurements.
