We conducted finite element (FE) analysis to develop a rotary swaging process to form the pointing part of hydrogen embrittlement- resistant steel rods. First, the shape and dimensions of the pointing section were determined by considering the drawing stress based on Geleji's equation. Second, the rotary swaging process was designed as a two-pass operation to disperse the excessive deformation of the drawn rods. Finally, the validity of the proposed two-pass schedule was verified by observing the dimensional changes in the pointed section, effective strain/stress distribution, and critical normalized damage value during the rotary swaging process.
