W artykule przedstawiono problem symulacji zachowania się materiału podczas przeróbki plastycznej z wykorzystaniem Metody Elementów Skończonych (MES). W odróżnieniu od konwencjonalnej symulacji MES do opisu zachowania się materiału wykorzystano model Crystal Plasticity (CP). Główną zaletą tego modelu jest możliwość jednoczesnego opisu umocnienia materiału oraz rozwoju tekstury podczas deformacji. Model ten jednak wymaga identyfikacji parametrów, które nie są powszechnie dostępne w literaturze. W przedstawionej pracy do identyfikacji parametrów wykorzystano metodę odwrotną. Zidentyfikowano parametry modelu dla monokryształów aluminium, a następnie zastosowano je do symulacji odkształcana polikrystalicznego aluminium. Otrzymane wyniki są zgod...
