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