Numerical Modeling of Electromagnetic Tube Expansion and Formability Assessment

Abstract:

In the present paper, an EMF numerical model has been developed following an uncoupled approach, being the Lorentz forces acting on the workpiece estimated by solving Maxwells equations and then transferred to solve the mechanical problem. For formability analysis, a fracture indicator based on the linear forming limit diagram was applied through the use of a post-processing tool developed by the authors. To illustrate the applicability of the implemented code in the fracture prediction, an example of electromagnetic tube expansion is presented. The corresponding numerical simulation is performed and its results are compared with experimental obtained from literature for a selected material.
