Simulation of metal forming processes with respect to MPP-systems
This paper describes the activities of INPRO in the field of metal forming simulation. INPRO, as a subsidiary of Daimler-Benz AG, Volkswagen AG, Krupp Hoesch Stahl AG, Hoechst AG, Siemens AG and Voest-Alpine Stahl Ges. mbH. is concerned with advanced manufacturing technology innovations.
A short description of different approaches to sheet metal simulation is given. At INPRO the special purpose program INDEED (INovative DEEp Drawing) has been developed. Although INDEED is highly optimized for well established hardware-platforms, industrial demands require a further reduction of CPU-time.
The announcement of MPP-Systems rises the hope to dramatically speed up the numerical simulation. At present, INPRO investigates how much benefit could be obtained by using MPP-Systems for the simulation of forming processes. The question arises, how much redesign and development of new algorithms are necessary to obtain a reasonable gain of performance.
