Abstract
In this study, the right-hand portion of the forming limit diagram (FLD) of a strain rate-sensitive FCC metal sheet with different combinations of two texture components, (001)[01¯0](cube component) and (112)[111¯](copper component) orientations and dislocation hardening effect at meso level, was predicted. Unlike the Marciniak-Kuczynski (M-K) model, no surface grooves in the sheet were assumed in the calculation. Because of the non-uniformity of microstructure in the thermal-mechanically processed sheet, narrow bands of grains with a similar orientation are assumed to exist instead. These bands behaved like a single crystal and deformed differently from their neighboring grains. The result from the simulation at the meso level was compared with two experimentally measured FLDs of a direct chill (O-temper) and continuous cast (H-temper) Al sheets.
