Abstract Scope

Edge ductility is a critical factor in the formability of advanced high-strength steels (AHSS) used in automotive stamping applications. This study presents a laboratory-scale methodology for quantifying edge ductility, leveraging the precision of Digital Image Correlation (DIC) to capture localized strain distributions. Specimens with varying edge qualities were prepared through controlled cutting processes and subsequently deformed using standardized punch geometries. DIC analysis enabled high-resolution mapping of strain gradients near the edge, facilitating the identification of fracture strain thresholds as a function of edge condition. The proposed method demonstrates strong potential for replicating industrial stamping scenarios, offering valuable insights for process optimization and simulation refinement in automotive forming operations.
