Warner T. Koiter

After primary and secondary education, he enrolled into Delft University of Technology in 1931, graduating with honours as a mechanical engineer in 1936.

These investigations led to his PhD thesis, On the Stability of Elastic Equilibrium, which was defended in Delft, November 1945; it was supervised by C. B.

As a consequence, its contents became only known to the broad scientific community after an English translation was edited by NASA 15 years later.

(Translation by Eduard Riks)[2] In 1949, he was appointed Professor of Applied Mechanics in Delft, where he stayed until his retirement in 1979.

Other contributions are in linear and non-linear thin shell theory, plasticity, elasticity and accompanying mathematics.
