Abstract

The high transient currents used by electromagnetic launch techniques produce a wide range of problems for modeling. The use of electromagnetic finite element (FE) analysis has allowed the electromagnetic effects to be modeled, and as a result the instantaneous heating effects. A technique for modeling the cumulative heating has been demonstrated for the 2-D case in Bath University´s MEGA electromagnetic FE program, by an FE application of the thermal diffusion equation. The 2-D thermal model has been modified and extended to modeling the 3-D case, and to the coupling between electromagnetic and thermal material properties
