Simulation of the Hotforming Process

The hotforming process or press hardening as it is also called is increasingly popular. The advantage by reaching very high strength parts whilst keeping a low weight is very interesting not only for the automotive industry. The process however, is a quite complex one, and the need for accurate simulation is even higher than for normal stamping. The complexity of the process means that you will find the same complexity in the simulation, including the hot stamping, the cooling and the metallurgical effects. This paper looks into the different aspects giving an overview of what is possible today, and what is needed for the future.
