||Contrarily to metalworking processes that are commonly used today, impulse metalworking processes typically utilize high pressures and short duration impulses that can be adapted to form, cut, join, weld, and emboss metals using lighter and more agile equipment. The fundamental nature of the short time-scale impulse also brings with it significant advantages. Increased forming limits, reduced springback and less wrinkling have for example been observed. Impact welding is a solid-state process that utilizes a high-speed collision to join metal components without simply melting the interface, leading to a strong weld region with no heat affected zones. Impulse forming and joining technologies can be driven by electromagnetic, electrohydraulic, explosive, hydro punch, vaporizing foil actuator, laser ablation or other novel mechanisms. The simulation of such processes often require complex multi-physics models. This mini-symposium will focus on recent numerical and experimental advances in impulse metalworking.
