abstract

Magnetic pulse process is used in the forming and welding processes. In order to predict the welding conditions, it is necessary to have an accurate modeling, which involves a coupling between magnetic and mechanical phenomena. In a first step, a numerical modeling of the magnetic field has been developed in the finite elements software ANSYS™, and the forces exerted on a tube have been predicted. The model has been validated by comparison with similar models. The influences of the different parameters have been studied. Then, the deformation of this tube has been predicted by a dynamical model in the finite elements software ABAQUS/Explicit™. As the tube shrinks, the mechanical and magnetic computings must be sequentially coupled in order to predict the forces exerted during the motion. Software MATLAB™ is used to couple the two models in the two softwares.
