Abstract：

The formability of Al alloy 6016-T4 was investigated at room temperature by combining experiment with numerical simulation. Then, the limit drawing ratio of 1.913 was got by sheet metal deep drawing experiments. Furthermore, the process of sheet metal drawing was simulated and analyzed by DYNAFORM finite element software, and the limit drawing ratio of 1.925 was obtained. The results of experiment and numerical simulation show that the thickness of rounded area in sheet metal decreases gradually with the increasing size of the sheet metal. At last, the contrast results of the punch stroke curve, deep drawing sheet thickness distribution and depth show that the simulation results fit well with the experimental ones. It provides a reference for further research and analysis of stamping process for automotive Al alloy.
