 The goal of my PhD was to model **Micro PlastoHydroDynamic lubrication** (MPH lubrication). This concept, which was first introduced by Mizuno and Okamoto [[#Bibliographical references|[1]]], consists in lubricant outflow from cavities at the asperity level. Azushima [[#Bibliographical references|[2]]] directly observed this phenomenon in plane strip drawing using a transparent die. Bech [[#Bibliographical references|[3]]] carried out experiments on a similar experimental set-up. He studied the effect of several parameters such as the strip thickness reduction, the drawing speed, the lubricant viscosity, etc.
-I used the in-house Finite Element (FE) software [[http://metafor.ltas.ulg.ac.be/|Metafor]] to reproduce Bech's experiments numerically. The model is able to predict lubricant escapes of the pocket backward and forward [[#Numerical modeling of MPH lubrication|(see video)]]. As in the experiments, several parametric studies were carried out on the thickness reduction effect, the slope of the lower tool and the drawing velocity, etc. These results show the model is capable of reproducing the trends observed experimentally by Bech.

 While I was setting-up MPH simulations, I performed [[#Fluid simulations|fluid]] and [[#Fluid-structure interaction simulations|fluid-structure interaction simulations]] to assess Metafor's validity on such configurations.
