#SAEsteel tweets: Paper 2010-01-0986: “A Practical Failure Limit for Sheared Edge Stretching of Automotive Body Panels”

...authored by Dajun Zhou, Chrysler Technology Center; John Siekirk, Chrysler Group LLC; Bernard S. Levy, Colorado School of Mines; Changqing Du, Chrysler Group LLC; Xiaoming Chen, US Steel; John McGuire, Chrysler Corp.

  • Sheared Edge Stretching Failure Limit-Chrysler, US Steel,Colorado School of Mines: measure thickness easier than grid

  • Sheared Edge Stretching Failure Limit- uniaxial tensile strain at edge. Higher stains give crosshatched necking bands

  • Sheared Edge Stretching Failure Limit- in DP600, FLCo is 2x thinning limit. In TRIP700, it is 3x. For the data shown

  • Sheared Edge Stretching Failure Limit-previous post-laser cut edge comparison: thinning limit about 10% in both grade

  • Sheared Edge Stretching Failure Limit-shearing rather than laser cut drops thinning limit by about 3%
