Finite element modeling has been conducted to investigate theeffect of die radius fillet, tube wall thickness, and friction coefficient on bothexternal and internal inversion forthealuminum tube. A 3D model was usedto build the contact pair for the aluminum tube and the steeldie. Due to theaxial symmetry, a 45osector for the contact pair has been chosen. It has beenfound that there is an important role for those parameters to govern theinversion process and the mode of deformation beside the value of theapplied force. No local buckling was seen in the external inversion incontrast with internal inversion. A good correlation for current results withexperimental one that has been got by others.
