Investigation of the Thermal Effects of Magnetic Pulse Forming using LS-DYNA

This paper shows the results o f LS-DYNA simulations and experimental studies of various sources of thermal effects occurring during magnetic pulse forming: theJoule heating of the eddy currents, the work of plastic deformation and the collision with the die. The obtained results allow quantifying the thermal effects and their influence on the mechanism of high-speed deformation: the technological plasticity of the forming process, the level of residual stresses during assembly operations, the mechanism of formation of welded joints, and so forth.
