Improvement of finite element model of Lubricated Contact Interfaces in Cold Rolling

The purpose of the internship is to build and improve a finite element modelling procedure to be able to reproduce locally a lubricated contact interface between strip and roll in the cold rolling process.

Accountabilities and activities: Based on previous work on finite element modelling of liquid entrapment at contact interfaces, the intern will be untrusted with the following missions:
• adapt these modelling conditions for cold rolling processes to analyse the impact of process parameters (rolling temperature, rolling speed, lubricant nature, thickness reduction) on oil behaviour at contact interface
• improve the model to better account for the effect of some process parameters (tangential velocity of the two surfaces in contact, non-deterministic surface roughness morphology)
