Summit on Predictive Modeling of Ductile Failure

Ravi-Chandar's picture

Place: AT&T Executive Education and Conference Center, University of Texas at Austin, Austin, TX

Dates: March 2-3, 2015

The 2nd Sandia Fracture Challenge was issued in May 2014. Participation in the Challenge was solicited through posting on iMechanica (see The purpose of the Challenge was to assess the capability of the solid mechanics community to predict ductile failure in a structural alloy, given some basic test results for material calibration. Fourteen teams submitted blind predictions for comparison with experiments performed by Sandia National Laboratories. A Summit will be held at the University of Texas AT&T Center ( in Austin, Texas on March 2nd and 3rd to (i) discuss the results, (ii) outline the various sources of discrepancy between models and experiments, (iii) debate areas for further development in the fracture community, and (iv) draft a joint journal article based on the outcome. The agenda for the meeting is given below. Participation in the Summit is open to two individuals from each team that submitted blind predictions as well as to any interested researchers who wish to attend as an “observer”. We particularly encourage young investigators and participants from underrepresented groups. Anyone interested in participating as an “observer” is requested to contact Professor Ravi-Chandar (
