| Abstract: | By using the rigid -viscoplastic finite element method,the distribution of equivalent strain, equivalent stress and temperature rise during the isothermal deformation of TC4 hollow component have been studied under different processing conditions. The results show that the deformation temperature and punch velocity have greater effects on the equivalent strain,equivalent stress,temperature rise and load of billet than friction. |
