Abstract: In order to investigate the deformation behavior of tube in electromagnetic forming with external die, in this paper, a numerical model based on the equivalent circuit method and finite element method was developed to simulate the tube deforming process, which was implemented through the coupling of MATLAB 2015a and ANSYS 15.0. Results showed that the deformation behavior of tube, including deformation depth and end flowing, is influenced by the distribution of Lorentz force, and the effect of the external die, which includes the restraining of radial expansion of tube, and the friction force generated from the contact of tube and die.
Keywords: Electromagnetic forming, current filament method, finite element method, lorentz force distribution, friction force
