Newly Developed Hole Expansion Test Accurately Simulates Edge Cracking in AHSS

October 6, 2020

With advanced high-strength steels (AHSS), standard formability tests yield insufficient data to determine the failure strain that triggers edge cracking. EWI has successfully evaluated a new testing method on DP780 steel which has the potential to help the automotive industry reduce design time, scrap rates, and other costs.

New Method for Determining Failure Criteria for Edge Cracking of AHSS, written by J. Clare Gu, describes how EWI developed this unique approach. You may view this paper, for free, by completing the form on this page.
