In this paper we study the Saint-Venant torsion problem for hollow homogeneousisotropic cylinders with thin doubly connected cross-section. By using the framework of the r-convergence of functionals, the classical theories of Bredt and of the sectorial areas are shown to be the variational limit of the torsion problem for cylinders with a hollow cross-section of vanishing thickness.

Abstract
In this paper we study the Saint-Venant torsion problem for hollow homogeneousisotropic cylinders with thin doubly connected cross-section. By using the framework of the r-convergence of functionals, the classical theories of Bredt and of the sectorial areas are shown to be the variational limit of the torsion problem for cylinders with a hollow cross-section of vanishing thickness.File in questo prodotto:
