European Association for Structural Dynamics

Last updated

The European Association for Structural Dynamics (EASD) is a professional body founded in 1990 to bring together members of structural dynamics community from all over Europe.

Structural analysis is mainly concerned with finding out the behavior of a physical structure when subjected to force. This action can be in the form of load due to the weight of things such as people, furniture, wind, snow, etc. or some other kind of excitation such as an earthquake, shaking of the ground due to a blast nearby, etc. In essence all these loads are dynamic, including the self-weight of the structure because at some point in time these loads were not there. The distinction is made between the dynamic and the static analysis on the basis of whether the applied action has enough acceleration in comparison to the structure's natural frequency. If a load is applied sufficiently slowly, the inertia forces can be ignored and the analysis can be simplified as static analysis. Structural dynamics, therefore, is a type of structural analysis which covers the behavior of structures subjected to dynamic loading. Dynamic loads include people, wind, waves, traffic, earthquakes, and blasts. Any structure can be subjected to dynamic loading. Dynamic analysis can be used to find dynamic displacements, time history, and modal analysis.

Activities

EASD oversees the organization of the European Conferences on Structural Dynamics (EURODYN) that will be held at three (or four) year intervals. These conferences shall be devoted to theoretical developments and applications of structural dynamics to all types of structures and structural materials.

A vactrain is a proposed design for very-high-speed rail transportation. It is a maglev line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high speeds with relatively little power—up to 6,400–8,000 km/h (4,000–5,000 mph). This is 5–6 times the speed of sound in Earth's atmosphere at sea level. Vactrains might use gravity to assist their acceleration. If these trains achieve the predicted speeds, they could surpass aircraft as the world's fastest mode of public transportation.

Structural loads or actions are forces, deformations, or accelerations applied to a structure or its components.

Minkowski Prize

The Minkowski Prize is given by the European Association for the Study of Diabetes (EASD), in recognition to research which has been carried out by a person normally residing in Europe, as manifested by publications which contribute to the advancement of knowledge concerning diabetes mellitus. The Prize honors the name of Oskar Minkowski (1858–1931), a physician and physiologist who was the discoverer of the role of pancreas in the control of glucose metabolism. It is awarded annually since 1966 and the winner is invited to pronounce a Minkowski Lecture during the EASD Annual Conference. It is traditionally seen as the most prestigious European prize in the field of diabetes research.

The Shock and Vibration Information Analysis Center (SAVIAC) is a U.S. Government organization established by the U.S. Navy Office of Naval Research on 20 December 1946. SAVIAC's purpose is to promulgate information on the transient and vibratory response of structures and materials. This broad field includes such technical areas as the testing, analysis and design of structural or mechanical systems subjected to dynamic conditions and loading such as vibration, blast, impact, and shock for various agencies in the U. S. Government including NASA, the Department of Energy (DOE), and the Department of Defense (DOD). The organization sponsored the professional journal Shock and Vibration Journal and currently sponsors and publishes the professional journal Journal of Critical Technology in Shock and Vibration. SAVIAC also sponsored and published a series of monograms addressing different aspects of shock and vibration. In 2012 SAVIAC became inactive as a result of new Department of Defense cost-cutting regulations limiting DoD sponsorship and participation of conferences and workshops. SAVIAC has been succeeded by an industrially-funded and managed "Shock and Vibration Exchange" SAVE.
