EPM for solid state forming processes

Teacher François Bay, Hans De Keulenaer


The next course in our techwatch series on Electromagnetic Processing of Materials (EPM) deals with the use of computational modelling and optimization for designing EPM solid state processes. Strong multiphysics couplings involved in these processes make their design and optimisation rather tricky.

In this course you'll learn about the kind of modelling techniques used in software modelling tools, which techniques can be suited to deal with the processes you wish to model, and how you can improve your design stage with these tools.

Course details

You will first get an introduction to modelling of electromagnetic couplings in forming processes; electromagnetic/heat transfer couplings as in induction heating processes, electromagnetic/solid couplings as in magnetic pulse forming processes.

We shall then introduce some numerical techniques commonly used in commercial software to deal with these processes. Space discretization techniques (full finite element vs. coupled finite element/boundary element) as well as time discretization schemes (full time integration vs. harmonic approaches) will be discussed. The issue of computational time reduction techniques will also be addressed.

Practical examples of use for design in industrial applications will then be described. We shall first introduce a case regarding induction mass heating processes aiming at minimizing energy losses. A second example will deal with optimisation of induction heat treatment applications aiming at controlling the final metallurgy of the part produced. A last example will focus on the control of magnetic pulse welding processes in order to ensure final quality of the welded product.
