Arpad Nadai

Arpad Ludwig Nadai (born April 3, 1883 in Budapest , † July 18, 1963 in Pittsburgh ) was a Hungarian-American mechanics professor.

Nadai studied at the University of Budapest and then at the TU Berlin , where he received his doctorate in 1911. In 1918 he went to the Institute for Applied Mechanics at the University of Göttingen , headed by Ludwig Prandtl , where he became a professor in 1923. In 1927 he went to the USA, where he succeeded Tymoshenko at the Westinghouse laboratories .

Nadai was a pioneer of plasticity theory , about which he wrote a textbook which, in English translation, was the first book on plasticity theory in English in 1931. It covers applications to metals as well as in the geosciences.

In 1958 he received the Tymoshenko Medal and in 1960 the Elliott Cresson Medal.

The American Society of Mechanical Engineers (ASME) has awarded the Nadai Medal for materials scientists since 1975 .
