Electromagnetic forming: a new coupling method

The EMF process is a deformation process at high speed, which involves coupled electromagnetic, mechanical and thermal problems. Due to the complexity of these couplings, the simulation of the process via FEM is a not a straightforward question. Nowadays the few commercial softwares that are able to simulate the multiphysics problem show certain limitations. That is why we propose a new simulation approach that solves the above mentioned limitations while maintaining a good correlation with the experimental results. The first part of the paper will describe our new approach based on the softwares Maxwell 3D® and Pam-Stamp2G®, and compare its results with the ones obtained with an automatic coupling of two commercial softwares (SysMagna® and Pam-Stamp2G®). The second part of the paper will show the comparison between the results of the new approach and the experimental ones, and the benefits of it for an industrial use.
