| Description | Journal: Iop Conference Series: Materials Science and Engineering Tensile tests were performed on aluminum alloy 2024 (AA 2024) using a Gleeble-1500 thermal-mechanical simulation system at high temperatures of 350, 400 and 450 °C and strain rates of 0.01, 0.1 and 1 $s^{−1}$. True stress-strain curves of AA 2024 were obtained. Forming limit curves (FLC) of AA 2024 were theoretically predicted based on Marciniak–Kuczynski (M–K) groove theory. In addition, the predicted curves were validated using the Nakazima method, and the effects of temperature on the FLC were analyzed. The results show that the curves predicted based on the M–K theory were in relatively good agreement with the experimental data. The forming limit of the AA 2024 sheet first increased, reached a maximum at 400 °C, and then decreased as its temperature increased. |
