Warner T. Koiter

Warner Tjardus Koiter ( born June 16, 1914 in Amsterdam, † September 2, 1997 in Delft ) was a Dutch engineer scientist for mechanics. He was a professor at the TU Delft.

Life and work

Koiter was the son of a teacher and grew up in Zutphen. He studied from 1931 Engineering (Mechanical ) at TU Delft, where he graduated in 1936 with distinction made ​​. After that, he was an engineer at the National Aircraft Research Institute in Amsterdam ( Rijks study service voor de Luchtvaart later Nationaal Lucht -en Ruimtevaartlaboratorium, NLR) in A. van der Neurt, from 1938 at the Patent Authority and from 1939 at the National Civil Aviation Authority, where he was the Head of engineering department was. During the Second World War he worked again on precursor Institute of NLR, which led to his dissertation at Cornelis B. Biezeno at TU Delft in 1945 ( Over de Stabiliteit van het Elastic Even Wicht, stability of elastic equilibrium, Dutch). The dissertation was completed in 1942, but he waited until after the crew with the filing because he wanted to not swear allegiance to the occupying power. It was also in 1960 translated into English and published by NASA, after he had reported in the late 1950s at Harvard University on their results. In 1949 he became Professor of Applied Mechanics at the Technical University of Delft, where he created specially for him on a chair for the theory of strength and stability of structures changed ( because after the student riots a retreat from the University was considering ) and 1979 emeritus 1973.

He was an internationally recognized expert in mechanics and received both the Von Karman Medal ( 1965) and the Timoshenko Medal ( 1968). At first he was known for his fundamental studies of the elastic equilibrium in continua (especially with non-linearities in the transition to the crease area), he dealt with linear and nonlinear shell theory and other problems of the theory of elasticity and plasticity theory.

He was a member of the Royal Netherlands Academy of Sciences, the Royal Society (1982 ) and the National Academy of Engineering. 1996 founded the American Society of Mechanical Engineers (ASME ), the Warner T. Koiter Medal with him as the first prize winner in 1997. A Mechanics Institute of the TU Delft is named after him. He was honorary doctorates from the universities of Glasgow, Bochum, Ghent and Liège.

His doctoral counts Jacob Willem Cohen.
