Abstract

It is known that the classical technical theories of Bredt and of sectorial areas are the variational limit of the Saint‐Venant torsion problem for hollow homogeneous isotropic cylinders with thin doubly connected cross‐section when the wall thickness reaches zero. The main goal of this paper is to prove that the same result remains true for thin tubes with multicell cross‐section.

Sommario. E’ noto che le classiche teorie tecniche di Bredt e delle aree settoriali sono il limite variazionale del problema della torsione alla De Saint‐Venant per cilindri lunghi con sezione cava biconnessa quando lo spessore della parete tende a zero. In questo lavoro si estende il risultato alle sezioni multiconnesse con ordine di connessione qualsiasi.
