Objectives

This program focuses on modelling and simulation tools to metal processing analyse. Students and specialists will use current commercial softwares dedicated to specific processing operations to address the reliability and the relevance but also the limits of these commercial softwares. a rigorous formation for the students in casting and miscellaneous techniques (powder metallurgy, welding, thixoforming, thermal spraying…), physical mechanisms and induced microstructure (1) to model and simulate these processing and (2) to predict the in-life mechanical properties of components.

Targets

This course can be directly applied to liquid, semi-liquid and solid metal processing: casting (sand casting, die casting), powder metallurgy (sintering, metal injection moulding…), welding, high energy processes, sheet forming operations (rolling, stamping, light cutting …), bulk materials forming operations (forging, extrusion, drawing …) and machining. Current industrial areas are aeronautics, transportation, nuclear engineering, energy, biomedical engineering, containers, structures …
