However, several research gaps remain unaddressed for the industrialization of this technology. Firstly, there is a lack of experimental validation regarding the impact of stress reduction on springback. Secondly, the potential effect of the skin-effect on the current metrics of stress reduction needs to be evaluated. Additionally, a post-forming electrically assisted elastoplastic material model is necessary for further technology development in stamping processes. This study tackles these challenges by utilizing AA5754H22 as a reference material and integrating a comprehensive experimental campaign with finite element numerical models and empirical material model developments. Our findings confirm that PFEPE facilitates a significant reduction in springback, achieving approximately a 100% reduction. Although the skin-effect introduces non-uniform current flux density distribution, its impact at the macroscopic level is negligible for the studied thin samples. While the numerical results of springback fails to accurately replicate experimental results, the developed material model aligns well with experimental trends. 1872-7743 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=177954 https://hdl.handle.net/20.500.11984/6672 Metal forming electroplasticity springback aluminium alloys ODS 9 Industria, innovación e infraestructura ODS 12 Producción y consumo responsables AA5754 aluminium alloy springback reduction by post forming electro plastic effect (PFEPE)
