Kyūichirō Washizu

Kyūichirō Washizu ( Japanese 鷲 津 久 一郎 , Washizu Kyūichirō ; * March 12, 1921 in Owari - Ichinomiya , Aichi Prefecture , Japan ; † November 25, 1981 in Tokyo ) was a Japanese aircraft engineer.

Washizu attended the third state school in Kyoto and studied engineering at Tokyo University from 1940 to 1942 . He then was a lecturer in the aircraft technology department and from 1947 to 1958 assistant professor. From 1953 to 1955 he completed postgraduate studies at the Massachusetts Institute of Technology (MIT) and received his doctorate in 1957 from the University of Tokyo (dissertation: Approximate solutions in elastomechanics (Japanese)). From 1958 until his retirement in 1981 he was professor of aircraft construction at the University of Tokyo. He then held an honorary professorship there and, shortly before his death, a professorship at Osaka University.

He dealt with methods of calculus of variations in the fundamentals of structural engineering, plasticity and elasticity theory, which had a great influence in the theory of finite elements in statics. The generalized variation principle developed by him is named after him and Hu Haichang .

In 1960 he was visiting scholar at MIT and he was visiting professor at the University of Washington in 1962 and at the Georgia Institute of Technology in 1979 .

1979/80 he was President of the Japanese Institute for Aviation Research.
