Hencky全量理论

Heinrich Hencky (2 November 1885 – 6 July 1951) was a German engineer. Born in Ansbach, he studied civil engineering in Munich and received his PhD from the Technische Hochschule Darmstadt. In 1913, he joined a railway company in Kharkiv, Ukraine. On the outbreak of World War I he was interned. After the war he taught at Darmstadt, Dresden and at Delft in the Netherlands. At Delft University of Technology he worked on slip-line theory, plasticity and rheology, for which h… Web23 feb. 1995 · Hencky's strain measure as a consequence arising from the conservation of energy. Truesdell and Toupin (1960, pg. 269) point out that Hencky's logarithmic strain measure had, up to that point in time, not been applied without difficulties be-cause of its complexity in evaluation. With computers now being readily available, such a …
