The industrial forming simulation used today is the result of a development process during the last two decades. A main focus of this process was the continuous optimization to characterize the mate­rial properties. The presentation will give an overview of the simulation technology challenges arising from the need to improve bridging of the gaps between material data and computational technology. Furthermore, an integrated technology pathway from the perspective of simulation requirements, material characterization needs, simulation technology innovations and impacts of those requirements on the accuracy of practical applications in the automotive world is discussed. The presentation will feature industrial examples to rein­force the topics of the paper.

Stosowane obecnie symulacje numeryczne procesów technologicznych są wynikiem prac prowadzonych w minionych dwóch dekadach. Szczególny nacisk podczas rozwoju symulacji numerycznych kładziono na poprawę modeli materiałów pod kątem optymalizacji uzyskiwanych własności wyrobów gotowych. Celem niniejszej pracy jest omówienie wyzwań pojawiających się podczas opracowywania takich modeli. Przedmiotem niniejszej pracy jest również dyskusja na temat zintegrowanego podejścia do analizy, które obejmuje określone wymagania materiałowe, innowacje w technologii produkcyjnej oraz innowacje w modelach numerycznych. Wpływ dokładności uzyskiwanych wyników na ich praktyczne wykorzystanie jest przedstawiony na przykładzie przemysłu samochodowego.
