Abstract
This paper describes a methodology for using two finite element (FE) codes, MAGTRPL and DYNA, to perform electromechanic, thermal, and structural modeling of railgun solid armatures. We analyze subscale armature experiments and present results that begin to identify the important engineering limits for materials used in armature fabrication
