Velocity limits of a solid armature in a railgun are the result of temperature and internal forces which surpass the yield strength of the material. A two-dimensional finite-element model for the magnetic and temperature fields in a railgun is presented for several rail and armatures designs. Copper rails and a molybdenum armature are identified as candidates for future solid armature testing. All simulations are performed for a 1/2-inch-square-bore railgun.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
