An example of successful research in cooperation with industry is the research concerning modelling and simulation of the press hardening process. This research has mainly been conducted in cooperation with Gestamp Hardtech, formerly SSAB Hardtech, and its customers in the automotive industry such as Volvo and Ford. Gestamp Hardtech is the world leading company in automotive ultra-high strength components manufactured by the press hardening process. The company had the first patents and industrialised the process and introduced the first press hardened automotive component in 1986.
The knowledge and methodological framework of modelling and simulation has now reached the point where it is possible to simulate a complete thermo-mechanical process such as the press hardening process and the methods are implemented in the industrial product development process. The developed models and methods are implemented in the commercial FE-code LS-Dyna, used world-wide in e.g the automotive industry for forming and crash simulations.
High temperature forming of titanium sheets for aircraft engine applications is another application of the research at Solid Mechanics. In two consecutive projects within the Swedish National Aeronautical research programmes NFFP4 and NFFP5, new thermo-mechanical forming processes have been developed based on material modelling and detailed numerical analyses. Based on the technologies developed within the consortium, Degerfors Formnings AB (Deform), ITE Fabriks AB, Permascand AB, Volvo Aero Corporation, IUC i Olofström AB and Luleå University of Technology, commercial components have been produced for the new generations of aircraft engines that will be in operation shortly.
