| Abstract: | Based on synthetically considering the coupled thermo-mechanical relations between temperature and deforming, a numerical simulation of the forging process for the special long cone-shaped workpiece of Al-5.44Mg-2.15Li-0.12Zr alloy at high temperature was conducted by using the rigid visco-plastic finite element method. The relations between the total load and the displacement during the forging, and the distributions of stress, strain, temperature and strain rate, which can provide useful information for the process design, are obtained. |
