The cash prize will be donated to the “Northwestern University Mechanical Sciences Donor Advised Fund,” which was established with Northwestern University in 2019.
The fund will provide the annual Ted Belytschko Fellowship to one NU incoming graduate student and the bi-annual Thomas J. R. Hughes travel funds for USNCTAM and IUTAM.

America Makes and Air Force Research Laboratory
Announce Awardees of the Additive Manufacturing
Modeling Challenge Series


AFRL AM Challenge Series Improved Understanding of the
Internal Structure and Resultant Performance of
Metallic Components Produced by AM

Youngstown, Ohio — July 20, 2020. America Makes and Air Force Research Laboratory, Materials & Manufacturing Directorate Structural Materials, Metals Branch (AFRL/RXCM), proudly announce the awardees of the additive manufacturing (AM) Modeling Challenge Series with $235K to be divided among the awardees.

Launched in November 2019 and comprised of four individual challenges, the AFRL AM Modeling Challenge Series represented another innovative approach America Makes and AFRL are taking to advance the AM industry. The goal of the Challenge Series was to improve the accuracy of model predictions for metal AM, using INCONEL® nickel-chromium alloy 625 (IN625). Challenge participants were provided high-pedigree calibration and validation data sets needed to develop new models as it directly related to predicting the internal structure and resultant performance of AM metallic components.

“Going into the AFRL AM Modeling Challenge Series, we knew that the outcomes would potentially lead to significantly improved predictability and accuracy of models and simulations, and the qualification of AM process and materials,” said America Makes Executive Director John Wilczynski. “The awardees of these four challenges certainly made solid contributions. They improved our understanding of the micro- and macro-structure level variability that was needed to advance the accuracy of modeling and simulation for AM metal. We thank all those who participated and extend our congratulations to the awardees.”

The AFRL AM Modeling Challenge Series project team awardees are:

Challenge 1: Macro-scale Process-to-Structure Predictions
Dassault Systems Government Solutions Corp.

Challenge 2: Micro-scale Process-to-Structure Predictions
The Wing Kam Liu Group at Northwestern University

Challenge 3: Macro-scale Structure-to-Properties Predictions
QuesTek Innovations LLC

Challenge 4: Micro-scale Structure-to-Properties Predictions
University of Utah, Carnegie Mellon University, and Los Alamos National Laboratory
