摘要: This paper focuses on a comparison between different modelling approaches to predict the forming limit diagram (FLD) for sheet metal under linear strain path using recently introduced orthotropic yield criterion BBC2003 (Banabic D et al 2005 Int. J. Plasticity 21 493–512). The FLD models considered here are finite element based approach, well known Marciniak–Kuczynski model, modified maximum force according Hora (1996 Proc. Numisheet'96 Conf. (Dearborn/Michigan) pp 252–6), Swift's diffuse (Swift H W 1952 Mech. Phys. Solids 1 1–18) and Hill's classical localized necking approach (Hill R 19–30). of an AA5182-O aluminium alloy has been determined experimentally in order quantify predictive capabilities mentioned above.
