Effect of High-Speed Shearing on Edge Formability of AHSS

December 18, 2019

A recurrent problem associated with the stamping of advanced high strength steel (AHSS) is edge cracking. The shearing process damages and hardens the edges of AHSS blanks, resulting in lower edge formability.

Recently, studies have been conducted at EWI on ways to improve edge formability of AHSS. Findings demonstrate that high-speed shearing can significantly improve edge formability. A paper by EWI associate Clare Gu, Effects of High-Speed Shearing on Edge Formability of AHSS, discusses the research and results of this work.
