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).

Predictive Theoretical and Computational Approaches for Additive Manufacturing: Proceedings of a Workshop is now available for download or purchase. This workshop was held at the National Academies' Keck Center in Washington, DC over three days in October 2015.

ICTAM 2016
in Montréal: August 21-26
The USNC/TAM was proud to host a Mentoring Breakfast at the 24th International Congress of Theoretical and Applied Mechanics (ICTAM 2016), held August 21-26, 2016 in Montréal, Canada. 46 early career professionals and mentors networked at the breakfast, during a session facilitated by USNC/TAM member Wendy Crone.

Nadine Aubry of the United States was selected as the next president of IUTAM. Dr. Aubry is a current member of the USNC/TAM, and is also a Fellow of the American Physical Society (APS) and the American Society of Mechanical Engineers (ASME). She is Dean of the College of Engineering and a University Distinguished Professor at Northeastern University.

The IUTAM Bureau Prize for best lecture in Solid Mechanics by a young scientist was awarded to Professor Stavros Gaitanaros. Dr. Gaitanaros is an Assistant Professor at Johns Hopkins University in Baltimore, and was recognized for his work on the effect of polydispersity on the crushing of open-cell random foams.

New Recent Trends in Mechanics Report Published in 2016
The USNC/TAM has initiated a new series of periodic reports, Recent Trends in Mechanics. Report proposals are due April 15th of each year. More information on the types of reports included in the series and report proposal guidelines can be found on the Reports: Recent Trends in Mechanics webpage.

The latest Recent Trends in Mechanics report, published in 2016, is titled Research Trends in Biological Fluid Dynamics (PDF). All previous reports can be found on the webpage.

USNC/TAM Awards 20 Travel Grants for International Congress of Theoretical and Applied Mechanics (ICTAM)
The USNC/TAM awarded 20 travel grants at $1,500 each to attend the 24th International Congress of Theoretical and Applied Mechanics in Montreal, Canada, August 21--26, 2016. The USNC/TAM sponsored a mentoring breakfast at ICTAM, where each travel fellowship awardee were paired with a mentor from the USNC or a senior U.S. mechanician, and a U.S. Reception. The mentoring breakfast was open to any U.S. early career professional attending the congress.

2018 U.S. National TAM Congress
The 18th U.S. National Congress on Theoretical and Applied Mechanics will be held from June 5 to June 9, 2018 at the Hyatt Regency O'Hare in Chicago. Northwestern University is proud to host this event.

2017 USNC/TAM Annual Meeting
The next USNC/TAM meeting will be held Friday, March 25 and Saturday, March 26 at the NAS building in Washington D.C.
Download the 2016 USNC/TAM Annual Meeting Presentations 
On April 22 and 23, the USNC/TAM held its 2016 meeting at the National Academies in Washington, D.C. Presentations from invited speakers are available for download here. If you are looking for the presentations from the 2015 USNC/TAM meeting, they are located here.

IUTAM Symposia and Summer Schools Selected at General Assembly 
The final proposal selections for the 2018 or 2019 IUTAM Symposia or Summer School were made at the 2016 IUTAM General Assembly, held during ICTAM in Montreal (August 21--26). For more information on symposia panel members, please visit the IUTAM Symposia and Summer Schools webpage.

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

Upcoming IUTAM Symposia in the U.S.
An IUTAM symposium will be held in the United States in 2017:
  • "Computational Particle Mechanics in Fluid and Solid Systems," jointly sponsored by IUTAM and AmeriMech, will be held at UC Berkeley in 2017. This invitation-only workshop will feature speakers on topics such as biomedical engineering, material design, and manufacturing processes. There will be time for roundtable discussions afterward.
