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).


2018 U.S. National TAM Congress and USNC/TAM Meeting
The 18th U.S. National Congress on Theoretical and Applied Mechanics will be held from June 4 to June 9, 2018 at the Hyatt Regency O'Hare in Chicago. Northwestern University is proud to host this event.

The next USNC/TAM Meeting will be held in conjunction with the U.S. Congress in Chicago, and will take place on Tuesday, June 5, 2018.

Call for Applications to Host 2022 U.S. National Congress
Every four years, the United States hosts a National Congress on Theoretical and Applied Mechanics. The next Congress, in 2018, will be held at Northwestern University in Chicago, IL. The USNC/TAM is currently looking for proposals from institutions that wish to host the 2022 Congress. The deadline for proposal submission is July 31, 2017.
The following factors will be considered when choosing a 2022 host, and ought to be addressed in the proposal:
  • Distinguished institution with strength in mechanics, institutional & departmental support, and faculty involvement
  • Previous experience hosting similar size conferences, if any, lecture hall(s) for large plenary sessions (~1000 seats), rooms for parallel technical sessions, spaces for banquet and/or social events
  • Housing options (on campus or nearby hotels and motels), transportation, airline service (give current rates from typical U. S. cities), rail or bus service, highway accessibility, climate and other factors that may influence the number of participants
  • Budget, estimated registration fee(s), expected revenue source(s), expected costs
If your institution is interested in hosting the Congress, please contact Tom Pence, chair of the site selection committee, at, 517-353-3889 for additional clarification prior to submitting your final proposal. Proposals should be submitted electronically to: Tom Pence ( and Linda Franzoni, Secretary of the US National Committee on Theoretical & Applied Mechanics (

Remembering Bruno Boley, USNC/TAM Ex-Officio Member and Lifelong IUTAM Member
Bruno A. Boley (1924-2017) passed away peacefully February 11 in Providence RI. He will be missed by his son, daughter in law, granddaughter and great grandson. Bruno was born in Italy, migrated to the United States on the last sailing of the Queen Mary before the outbreak of World War II in 1939, obtained the B.S. degree in Civil Engineering from City College of New York and the Sc.D. in Aeronautical Engineering from Brooklyn Polytechnic Institute in 1946. He was a professor in Civil Engineering at Columbia University (1952-1968), headed the Cornell University Department of Theoretical and Applied Mechanics until 1972 and then was Dean of Engineering at Northwestern University until 1986.

After his long scientific career, he devoted himself to historical pursuits culminating in the book "Wandering Through Europe: The Story of European Geographical Names" in 2008. He was a founding editor of the journal Mechanics Research Communications. His classic text "Theory of Thermal Stresses" (with Jerome Weiner) has educated countless generations of scientists. Among his many honors, he received the Worcester Reed Warner Medal in 1991 from the American Society of Mechanical Engineers for his outstanding contributions to the permanent literature of engineering. He was elected to the National Academy of Engineering in 1975. (Obituary text from, published from February 13-14, 2017.)

October 2016 Additive Manufacturing Workshop Held in China
WAM2016, short for the Workshop on Predictive Theoretical, Computational, and Experimental Approaches for Additive Manufacturing (WAM 2016), was held in Dalian, China from October 17--19, 2016. The National Natural Science Foundation of China (NSFC) and the Chinese Society of Theoretical and Applied Mechanics (CSTAM) co-sponsored the event.

The workshop is an extension of last October's "A Workshop on Predictive Theoretical and Computational Approaches for Additive Manufacturing" held in Washington, DC at the National Academies of Sciences, Engineering, and Medicine. Both workshops aimed to foster collaboration among professionals and undertake challenges within the field of additive manufacturing.

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.

Workshop participants Ade Makinde (GE Global Research Center), Tahany El-Wardany (United Technologies Research Center), Peter Olmstead (Georgetown University), and Joseph Beaman (University of Texas - Austin) were happy to answer additive manufacturing questions in a video for NAS.

All workshop media, including session videos, meeting agenda, and presentation PDFs, are listed on the 2015 Additive Manufacturing Workshop page. You can also 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
