The forming limit of AA5182 aluminum alloy in warm condition was predicted based on MK model combined with Hill48, Barlat89 and YLD2000 yield criteria, respectively, and the warm forming limit experiments of AA5182 aluminum alloy under different temperatures were conducted to obtain the forming limit data of material at different temperatures. Comparing the experimental result with the predicted result, it is considered that the Barlat89 yield criterion is more appropriate for predicting forming limit of AA5182 aluminum alloy in warm condition than other two yield criteria. Meanwhile, the influences of temperature and strain rate sensitivity index on the predicted result of [JP3]forming limit were analyzed. The result shows that the forming limit of material increases with the increasing of temperature and strain rate sensitivity index. Moreover, the strain rate sensitivity index has influence on the shape of the predicted forming limit of material.
