Abstract
The present study reports the influence of the athermal effects of electroplasticity on the bottom bending process when the Joule effect is minimized to negligible values. To do so a short-time current pulse generator, capable of inducing 300 A current pulses and a pulse duration of 50 mu s, was designed and manufactured. The materials studied were sheets of 1050-H18 aluminium alloy and X5CrNi18-10 stainless steel. A finite element analysis was done in order to characterize the different phases ...
