Development of mechanical measurement system applied for electroplastic effect research

Electrically-assisted manufacturing (EAM) is an emerging metal-manufacturing process which is promising in the automotive and aerospace industries. The process is based on the electroplastic effect that is supposed to reduce the stress needed in the forming and improve the ductility of the metal. In this paper, we develop an electroplastic measurement system to study the electroplastic effect of the A5083 aluminum alloy. And the effects of current density and the pulse width on the electroplasticity are preliminary investigated.
