| Abstract: | Metal plastic forming is a typical thermomechanical coupling process.Based on temperature governing equation, the thermomechanical coupling effects in metal plastic forming process is discussed in this paper.The temperature and equivalent strain in elastic-plastic cylinder during upsetting is numerically simulated by FEM. The effects of forming speed and initial temperature of billets on forming process are also discussed. |
