Heinrich Hencky

Heinrich Hencky ( born November 2, 1885 in Ansbach, † July 6, 1951 ) was a German engineer.

Life

Hencky studied from 1912-1913 at the Technical University in Darmstadt and received his doctorate there. 1913 Hencky went to a railway company to Kharkov (Ukraine) and was interned after the start of the First World War by the Russians as an enemy alien in a camp in the Ural Mountains. In the internment Hencky 1918 married a Russian woman.

At the Technical University of Dresden, he habilitated with a habilitation thesis on the stability of elastic plates. 1922 was followed by a brief period as a lecturer at the Technical University of Delft. He remained until 1929 in Delft. In 1923 he published his most famous work "On some statically determinate cases of equilibrium in three-dimensional bodies ."

He was 1930-1932 Professor of Mechanics at the Massachusetts Institute of Technology (MIT), where his theoretical approach to mechanics but at that time was little demand.

In 1936, on the recommendation of Hencky Boris Galjorkin back to the Soviet Union. He came to the Chemical Institute in Kharkov and then at the University of Moscow to the Institute of Ilyushin. Hencky in 1938 was reported to the German Reich. The Nazis dared Hencky not because of his many visits abroad. With the support of his brother Hencky could stay with MAN near Mainz and remained there until his death. On July 6, 1951 Hencky died while rock climbing.

Hencky is now regarded as a pioneer of continuum mechanics and rheology, specifically the theory of plasticity.
