U.S. National Committee FOR TAM

The U.S. National Committee on Theoretical and Applied Mechanics (USNC/TAM) represents the United States in national and international activities related to the broad science of mechanics, including related sciences, engineering and mathematics. It serves as a focal point for charting future priorities in mechanics related research, applications and education. It represents the United States in the International Union of Theoretical and Applied Mechanics (IUTAM).

Download the 2016 USNC/TAM Annual Meeting Presentations

Online registration opens approximately eight weeks before the workshop (early-mid March) and closes April 27, 2016. Two separate registrations are necessary for Wednesday and Thursday. This workshop is free for ASTM members, and costs only a small fee ($25) for non-members.
Register for the Wednesday (May 4) session here.
Register for the Thursday (May 5) session here.

Professionals in all aspects of the AM community (industrial, academic, government, regulatory, and funding agencies) interested in these areas are welcome to attend. For more information, please contact any of the workshop's three co-chairs: Steve Daniewicz at, Nima Shamsaei at, or Nik Hrabe at

Four NAS Workshop Participants Discuss Additive Manufacturing

Ade Makinde (GE Global Research Center), Tahany El-Wardany (United Technologies Research Center), Peter Olmstead (Georgetown University), and Joseph Beaman (University of Texas - Austin) answer your questions on additive manufacturing in a new NAS video.

Additive Manufacturing Workshop Media Available For Download
The recent USNC/TAM-hosted Workshop on Predictive Theoretical and Computational Approaches for Additive Manufacturing was a tremendous success. The three-day workshop featured 24 presentations from speakers in academia, industry, and government labs, and the Livestream workshop broadcast has already reached over 200 live and 1,700 total viewers.

All workshop media, including session videos, meeting agenda, and presentation PDFs, are listed on the 2015 Additive Manufacturing Workshop page. Or click below to browse and view the eight session videos.

As a result of this workshop, Lyle Levine, Project Leader of Additive Manufacturing of Metals at NIST, has proposed a series of benchmark tests and an accompanying conference series.  Dr. Levine's ideas for AM-Bench are loosely based upon his existing NUMISHEET benchmark test series, which has profoundly influenced the sheet metal field for over 25 years. The project, which aims to start developing AM standards, requires input from experts across the board in industry, national labs, and academia.

If you are interested in joining the planning committee, which will define the scope and organization of this series, please contact Lyle Levine at
