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
aluminum tube. A 3D model was used
to build the contact pair for the a
luminum tube and the steel
. Due to the
axial symmetry, a 45
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.
