Introduction of an Electromagnetism Module in LS-DYNA for Coupled Mechanical-Thermal-Electromagnetic Simulations

A new electromagnetism module is being developed in LD-DYNA for coupled mechanical/thermal/electromagnetic simulations. One of the main applications of this module is Electromagnetic Metal Forming. The physics, numerical methods and capabilities of this new module are briefly presented. This module is then illustrated on different simulations. A first set of simulations corresponds to a ring expansion experiment, which was performed at The Ohio State University, for which the code is compared with experimental results. A second example corresponds to a typical Electromagnetic Metal Forming of a thin metallic sheet.
