The 12th International Conference and Workshop on Numerical Simulation of 3D Sheet Metal Forming Processes (NUMISHEET 2020)

July 19-24, 2020 • Sheraton Centre Toronto Hotel • Toronto, Ontario, Canada

BM2 : Fracture Model Prediction of Nonlinear Forming Processes

This benchmark challenge consists of a set of 20 experimental strain paths extended beyond the point of fracture that are obtained from nonlinear tests on DP 1180 and AA 6xxx-T81. The extension is done using an algorithm that mimics the strain measurement error of the experimental data to avoid hints about when fracture occurred in each test. Participants are challenged to analyze these strain paths defined in terms of the strain tensor components in a coordinate system aligned to the RD of the sheet coil as they would analyze the same strain paths predicted in a finite element simulation to predict when fracture occurred, and if localized necking preceded the fracture, predict the strain at the onset of necking.

This study is now closed.

The organizers of NUMISHEET 2020 hold the health and well-being of our attendees as our highest priority. We have been closely monitoring COVID-19 developments, especially with concern for how the policies and recommendations from government and health organizations could impact our attendees. Currently, the plans for NUMISHEET 2020 are proceeding on schedule. Should any changes to the event be needed, we will update this statement and notify presenters and attendees promptly.
