Abstract
A numerical method for modeling the deformation and impact that occurs during the electromagnetic forming process is presented. The numerical model employs a strong coupling of the electromagnetic analysis with the plastic structural one. An electromagnetic finite element model is developed to modelise the time varying currents that are discharged through the coil in order to obtain the transient magnetic forces that are imparted to the work piece. The body forces generated by electromagnetic induction are then used as the loading condition to model the plastic deformation of the workpiece using a dynamic finite element modeling. According to the displacement and/or the deformation of the metal sheet, the modeling system is remeshed when a new step begins. Our iterative coupled model accurately predicted the final geometry of the sheet as well as the deformation at each time step.
