Three-dimensional finite element analysis of single-turn coil systems

The paper describes a multiphysical finite-element approach to simulation of the three-dimensional modelling of metallic structures that are transiently subjected to heavy electromagnetic loading, as in the metal forming industry. Electromagnetic, thermal and structural effects are all taken into account, and very good agreement is obtained in detailed comparisons with measurements from non-destructive experiments. Acceptable agreement also exists in the peak field prediction of destructive experiments, in which single-turn coils are used to generate ultrahigh magnetic fields, typically for use in solid-state experimental physics.
