In order to consider the motion of object deformation, an 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 are validated from a comparison with experimental data
