Predictions of forming limit diagrams using crystal plasticity models

Crystal plasticity models are used in conjunction with the Marciniak-Kuczynski approach to predict forming limit diagrams (FLDs) of different annealed aluminium alloy sheet (AA6xxx series) with various initial crystallographic textures. The numerically determined FLDs are compared with experimental data. Two distinct models are used for FLDs predictions. The first method involves the calculation of yield surfaces from a rigid-plastic rate …
