Comparison of Forming Limit Diagrams for FCC and BCC Materials using Taylor and Marciniak-Kuczynski Models
A comparison of forming limit diagrams (FLDs) for body-centered cubic (BCC) and face-centered cubic (FCC)
crystal structures is proposed in this paper. A numerical FEM-based determination of FLD including a polycrystalline model
is developed. The simulations in this work are based on elastic-viscoplastic Taylor polycrystal model and Marciniak-
Kuczynski approach. Time and efficiency of simulations are studied.
Key words - BCC and FCC sheets, FormingLimit Diagrams, Marciniak-Kuczynski model, Taylor model.
