Otto Föppl

from Wikipedia, the free encyclopedia

Otto Föppl (born April 6, 1885 in Leipzig ; † March 19, 1963 in Ilten ) was a German engineer and professor of technical mechanics at the Technical University of Braunschweig .

Life

Föppl was the son of August Föppl , he studied at the TH Munich with internships at Maffei in Munich and MAN in Augsburg. He received his doctorate in aerodynamics in 1911 at the Technical University of Aachen on the subject of wind forces on flat and curved plates . From 1909 to 1911 he was Ludwig Prandtl's assistant at his aerodynamic research institute in Göttingen. In 1911 he worked as a test engineer in Aachen and from 1913 as a patent engineer at MAN. During the First World War he was involved in the development of diesel engines for submarines, among other things, in Wilhelmshaven. From 1921 until his retirement in 1951 he was associate professor for vibration engineering and strength theory at the Technical University of Braunschweig, where he headed the laboratory for strength science. Otto Föppl also applied for his strength laboratory to be named after August Wöhler, the pioneer in the field of fatigue strength. The name was changed to "Wöhler Institute" in 1925. At that time, Föppl's "Wöhler Institute" was the first German institute to deal directly with the subject of dynamically loaded materials and constructions in mechanical engineering.

Since 1949 he was a full member of the Braunschweig Scientific Society .

In 1924/25 Adolf Busemann was his assistant. During this time, Busemann also did his doctorate with Otto Föppl. Ludwig Prandtl was his brother-in-law.
