The International Union of Theoretical and Applied Mechanics (IUTAM) is an international non-governmental, non-profit, scientific organisation that promotes theoretical and applied mechanics as a scientific discipline by organising congresses, symposia and summer schools.

It is a member of the International Science Council and thereby contributes to a global voice on science.

About Us

The International Union of Theoretical and Applied Mechanics (IUTAM) grew out of the Congresses and was founded in 1946 as an international non-governmental non-profit scientific organization. On 4 November 2022 it was incorporated as an Association with full legal status in Amsterdam, the Netherlands.

New Horizons

Solid Mechanics, Fluid Mechanics and Dynamics has underpinned a number of new technologies over the past decade from air, sea and land vehicles to modern infrastructure and medical devices.
