Recent developments in transient magneto-structural integrated analysis for fusion applications

Three different numerical approaches modeling the mutual field-structure interactions during transient electromagnetic events are presented. The application of these approaches to simple plate models simulating flexible conducting components of fusion devices shows that magnetic damping is encountered when coupling effects between, eddy currents and plate motion are taken into account. This damping increases with the applied magnetic field, modifying the mechanical behavior. It is noted that the complexity of electromagnetomechanical modeling can be overcome by the use of an integrated design/analysis system (currently under development) that allows the combined use of different-purpose computer codes.>
