Numerical Study of Damage Evolution and Failure in an Electromagnetic Corner Fill Operation

A simple model to simulate electromagnetic sheet free bulging process

“…The mechanical problem is then solved using a commercial finite element code. With this simple model, the finite element simulations performed by Imbert et al [10] are in agreement with the experimental results.…”

“…In agreement with Imbert et al [10], we have decided to consider the electromagnetic and the mechanical aspects of the process as two independent problems. The EMF test studied in this paper is the free bulging electromagnetic sheet process proposed in Ref.…”

“…The 'loosely coupled' model or the 'fully coupled' allows accurate simulations of the EMF sheet process. But more simple models also give fine results [10,11]. In these simple models, the EMF sheet process is treated as two independent problems: an electromagnetic problem and a mechanical problem.…”

“…In these simple models, the EMF sheet process is treated as two independent problems: an electromagnetic problem and a mechanical problem. For instance, in the work of Imbert et al [10], the magnetic pressure distribution has been estimated from the analytical work of Al-Hassani [12] and it is used as a load in the mechanical problem. The mechanical problem is then solved using a commercial finite element code.…”
