| Abstract | ||
| Finite element modeling has been conducted to investigate the effect of die radius fillet, tube wall thickness, and friction coefficient on both external and internal inversion for the aluminum tube. A 3D model was used to build the contact pair for the a luminum tube and the steel die . Due to the axial symmetry, a 45 o sector for the contact pair has been chosen. It has been found that there is an important role for those parameters to govern the inversion process and the mode of deformation beside the valu e of the applied force. No local buckling was seen in the external inversion in contrast with internal inversion. A good correlation for current results with experimental one that has been got by others. | ||
