Carlo Alberto Castigliano

from Wikipedia, the free encyclopedia

Carlo Alberto Castigliano (born November 8, 1847 in Asti , † October 25, 1884 in Milan ) was an Italian builder , engineer and scientist .

Life

He came from a very humble background and lost his parents before he even left school. He earned his first money with book translations and tutoring. He was a mechanics teacher in Terni from 1867 to 1870 and then attended the Polytechnic Institute in Turin from 1870 to 1873 . After studying engineering and mathematics for three years , he received his engineering degree early.

Castigliano

He formulated a well-known theorem of technical mechanics , Castigliano's 2nd theorem , which is used to calculate deformation in statically indeterminate systems. The set is suitable for the calculation of any generally loaded statically indeterminate systems and for the calculation of deformation quantities at certain (discrete) points and is of major importance in the calculation of the bending in structural engineering and technical mechanics ; he played a central role in the dispute over the foundation of classical structural engineering.

Castigliano's Theorem

The set of Castigliano consists of several parts and essentially says: "The partial derivative of the strain energy of a load group to a single load provides the associated shift."
