One may think that, after nearly three decades of research & development on hot sheet metal forming technology, all important issues that lie behind the superior crash performance and lightweight design of press hardened parts have already been investigated sufficiently. There are even some who, with respect to the increasing availability of cold-deformable steel grades with complex microstructure, consider this technology as transient and therefore regard further research & Simulation I Oobias Olsson An LS-DYNA material model for simulations of hot stamping processes of ultra high strength steels Laurent Durrenberger, Joël Wilsius and Philipp Hein Impact of the constitutive model on the hot-forming numerical predictions of Usibor1500P Iñigo Aranguren, Maite Santos, Sonia Varela, Beatriz González, Marian Gutiérrez and Borja Fernández Evaluation and optimization of the use of simulation software codes for the design of a tooling for a hot stamped industrial part Thomas Schönbach and Michael Kerausch Effective usage of simulation techniques for the layout of hotforming processes Materials II Hans-Gerd Lambers, Sergej Tschumak, Hans Jürgen Maier and Demircan Canadinc Tensile properties of 51 CrV 4 steel in martensitic, bainitic and austenitic state Hermann Autenrieth, Norman Herzig, Jürgen Hoffmeister, Volker Schulze and Lothar W.

Reality looks different. Today, hot metal forming technology constitutes the most efficient technological route to achieving highest strength with corresponding high level of geometrical complexity and will undoubtedly strengthen its technological role in sheet metal forming drastically in the future. The ongoing trend towards further system consolidation, especially for body-in-white structures with significantly higher functional integration on single component level, emphasises this strongly. Increasing demand for materials with greatly improved properties and efficient and predictable processes therefore stimulates intensive research in this field on an international level. A strong research community has already evolved constituting a driving force for innovation in hot sheet metal forming. As the second in a series of international conventions, the 2nd International Conference on Hot Sheet Metal Forming of High-Performance Steel - CHS2 2009 therefore highlights multiple aspects from a scientific as well as an industrial viewpoint.
