Basic physical processes involved in EMF, such as e.g. inelastic and hardening behavior or inertia, have been considered in previous works [1, 2]. The purpose of the current work is the investigation of temperature development during EMF and a possible reduction in the yield stress due to electric currents. While thermoelastic and viscoplastic effects are well-understood in this context [3], the possible influence of electric currents on dislocation motion, generally referred to as the electro-plastic effect [4, 5], is still an unresolved issue. In agreement with previous works [e.g., 6], it is concluded here that such an effect is at most of second-order and can most likely be safely neglected in the modeling and simulation of industrial EMF.enelectromagnetic metal formingelectroplasticitymagneto-thermo-inelastic coupling620670Text
