Abstract：

As the most comprehensive and simple criterion of material forming, forming limit curves have become an important tool to measure the formability and solve the stamping problems. The uniaxial tensile test, cupping test and bulging experiments were conducted with aluminum alloy AA5182-O, and the forming limits strain points of corresponding methods were obtained, further the fitted experiment forming limit curves were compared with each other, finally, the stamping was conducted to verify the accuracy of the test forming limit curves. The study shows that the forming limit curves obtained by uniaxial tensile test and cupping test are lower than that by bulging experiments. However, the limit point obtained by cupping test has the equivalent limit point while the bulging limit curve lacks of it. After compared the stamping failure limit points with the experiment forming limit curves, the forming limit curves obtained by the single drawing and cupping tests are more accurate than that by the bulging experiments.
