The paper gives some insight into modelling of selected applications in heat supported forming processes of sheet metal and closed profiles.
Simulation strategies and computational results are discussed and, by means of practical examples, the relevance of thermal boundary conditions and parameters is examined. Special attention must be given, during the tool design process, to the layout and dimensioning of cooling cannels, regarding to a targeted temperature control of the work-piece. In many cases optimized temperature guidance proves to be a prerequisite of efficiency and product quality. The presented results are realized using the commercials codes LS-DYNA, ABAQUS and ANSYS and verified by close-to-production prototypes.
