Finite Element Analysis of Cold Expanding of Hollow Thin-Wall Tube
The cold expanding diameter process was simulated by the software of DEFORM. The finite element model of tube and dies were built. The object position definition, the inter object setting, movement definition and simulation step were correctly set. The deformation, total velocity distribution and equivalent stress distribution were predicted. The numerical simulation results showed that the finite element analysis could exactly describe the plastic deformation and stress distribution during the forming process.
