Abstract
The electroplastic effect on AA1050 aluminium alloy sheets was investigated with the aim of decoupling the electroplastic and thermal behaviour due to Joule effect in electrical-assisted forming. Different stress triaxiality conditions, obtained using smooth, notched and single shear specimens, were tested applying a range of Direct Current densities to demonstrate that the material formability can be enhanced just thanks to the electroplastic effect. The obtained results were supported by TEM analysis of the dislocation density.
