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 fin ite 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 s ystem study. The simulation of deforming process is obtained by the modific ation of the ME size through the modification of its matrix while retaining the same mesh topology. This modification is the consequence of the viscop lastic problem solution. The modeling results rite validated from a compari son with experimental data.
