A critical review on hole expansion ratio
Materialia, 2020Abstract Materials resistance to edge fracture in intricate shape forming is commonly quantified by hole expansion ratio (HER). Hole expansion test is normally used to evaluate HER. To date, the governing factors of HER have not well understood regardless of its importance for automotive part manufacturing with advanced high-strength steels.

Effect of punch geometry on hole expansion ratio
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2019Stretch-flangeability of sheet metal is normally quantified by hole expansion ratio. Researchers have determined hole expansion ratio with various punch geometries such as conical, flat-bottom and hemispherical, and reported different hole expansion ratio values for identical test condition.
