Application of macro-element and finite element coupling for the behavior analysis of magnetoforming systems

In order to consider the motion of object deforming, the analytical and finite element coupling technique is used to study the magnetoforming process. The analytical solution given through the Macro-Element (ME) technique is done and applied to the case of an axisymmetrical electromagnetic forming system study. The simulation of deforming process is obtained by the modification of the ME size through the modification of its matrix while retaining the same mesh topology. This modification is the consequence of the viscoplastic problem solution. The modeling results rite validated from a comparison with experimental data.
