Abstract :
Upsetting is an important technics for improving the inner structure of metal. The stress, strain and temperature distribution can influence the effect of upsetting. To achieve good effect of upsetting, a prediction model of upsetting based on thermo-elastic-plastic finite element equation is built. The three-dimensional upsetting process is studied by using the method of finite element Lagrange analysis, analyzing the distribution of temperature, stress, and load in upsetting process. The simulation results can help to determine the parameters for upsetting and give an advice for upsetting process.
