Pyotr Fyodorowitsch Papkowitsch

Pjotr ​​Fjodorowitsch Papkowitsch , Russian Пётр Фёдорович Папкович , English transcription Petr Fedorovich Papkovich, (born April 5, 1887 in Brest-Litovsk ; † April 3, 1946 in Leningrad ) was a Soviet engineer and shipbuilding engineer .

Papkowitsch attended school in Samara and studied shipbuilding at the St. Petersburg Polytechnic, graduating in 1911. Then he was in the Russian Navy, deployed at the shipyards in St. Petersburg. In 1916 he became captain of the corps of shipbuilding engineers. He also taught at the Polytechnic from 1916 to 1930, from 1925 as a professor of ship mechanics. 1930 to 1939 he held the corresponding chair at the newly founded Institute for Shipbuilding in Leningrad. He also taught at the Naval Academy from 1920, and from 1934 as a professor of shipbuilding and ship mechanics. In 1935 he received the Russian doctorate (without examination). In 1940 he became Rear Admiral of the Shipbuilding Engineers.

He is known for his contributions to the theory of elasticity , especially the Papkovich-Neuber solution (1932, also after H. Neuber) of the homogeneous Navier-Cauchy equations .

In 1915 he received the Order of St. Stanislaus 3rd Class. He was a corresponding member of the Soviet Academy of Sciences (1933), received the Order of Lenin in 1943 and 1946 and received the Stalin Prize, First Class , in 1946 . In 1944 he became an "Honored Scientist" of the Russian Federation.
