Numerical Investigation of Tube Compression Electromagnetic Forming by Finite Element Method and Design of Experiment
Author(s):
Abstract:
Electromagnetic forming is a high energy rate forming process which is applied for manufacturing and assembly of many parts that are used in automobile and aerospace industries. In this process¡ the electromagnetic body forces (Lorentz forces) are used to produce metallic parts. In this article¡ the influence of important process parameters such as discharge voltage¡ friction coefficient¡ clearance between the tube and die¡ wall thickness and length of tube¡ on the radial displacement and workpiece thinning were investigated. The output of governing equations in the form of pressure applied on the part via a subroutine in a Fortran Program. A dynamic analysis using two dimensional axisymmetric models were performed and Johnson-Cook theory was applied to represent the effect of strain rate sensitivity and show the plastic behavior in the deformation process. Finally¡ the numerical results were compared with the results reported by other researchers and found a good agreement between them.
