    Hot stamping is a forming process used in the automotive industry to form structural
    parts. A sheet metal blank is austenitized in a furnace, formed at high temperatures (600-
    800 °C) and quenched in the press such that a martensitic structure is obtained. In this
    way, high strength (~1500 MPa) can be combined with good formability and good
    geometrical tolerances. However, due to forming at high temperatures, the friction is
    relatively high and tool wear is severe. The tool wear causes scratches on the parts,
    leading to lower heat transfer and high maintenance costs.
    In this thesis, the friction and wear mechanisms in hot stamping are addressed and a
    physics-based multi-scale friction model is coupled with FE analysis.
