, Harbin Institute of Technology, Harbin 150001, China)Abstract:The forming process was simulated numerically by ANSYS/LS-DYNA. The material flowing of tube-blank in the tube-compression process and the effect of the friction coefficient between die and tube-blank on the forming process were analyzed. The research results show that the flowing direction of tube-blank and the flowing direction......
