摘要：
An accurate material model is the basis for numerical simulation of stamping. By means of tensile tests in three directions, uniaxial compression tests and forming limit tests, the material property data of 5754 aluminum alloy is obtained. Based on the Voce hardening model, Barlat89 yield criterion and forming limit curves, the material model of 5754 aluminum alloy for stamping was established. With the Pamstamp-2G software, the stamping operation of automobile girders of 5754 aluminum alloy was simulated, which was compared with the actual stamping operation. The results show that the plastic strain calculated by the simulation is close to the experimental measurement one, the maximum thinning rate error is within ±10%, which verifies the reliability of numerical simulation. © 2020, Science Press.
