| 摘 要： | 1 Introduction A double-walled invertube is difficult to fabricate other than applying inversion process. Such kind of invertube can be used as impact energy absorbing element in transport vehicles, like aircrafts and automobiles. Reddy T Y1] did the analysis of Internal inversion and calculated the inversion load. Reid2] et al. examined nosing and internal inversion of cold drawn steel tube by the finite element package ABAQUS. Recently, Rosa P A3] et al. investigated Internal invers…

| Abstract: | A double-walled tubular component can be formed from a metal tube under axial compression by inversion. Numerical simulation and experimental investigation show that die radius is the predominant factor affecting the deformation process. For the given dimensions of 3A21 aluminium alloy tube, the feasible die radius varies between 2~4mm. The deformation process predicted by the finite element simulation agrees with the experiment results well. |
