Abstract
In the present study, electroplastic tensile behaviors of aluminum 5052-H32 alloy specimens with different gage dimensions are investigated under a constant electric energy density (electric energy per unit volume). The experimental results show that equivalent electric energy densities induce nearly identical electroplastic behaviors even with different gage dimensions (length, width, or volume). Additionally, the experimental results demonstrate that the electroplastic behavior of the selected aluminum alloy is best described by the electric energy density, which is a function of current density and current duration, rather than individual current density or current duration. The results of the present study suggest that the electric energy density may replace current density and current duration as a design parameter in electrically assisted forming processes.
