โฆ Synopsis
We obtain upper bounds for the torsional rigidity of an isotropic right cylinder whose ends are restrained against warping in terms of the Saint-Venant torsional rigidity, the polar moment of inertia and the lowest free membrane eigenvalue of the cross-section, the length of the cylinder and the elastic constants. They may be used to show that the two torsional rigidities tend to coincidence as the cylinder becomes infinitely long. Various other implications of the bounds are also discussed.
RI~SUMI~
Nous obtenons des bornes superieures pour la rigidit6/t la torsion d'un cylindre droit isotrope dont chaque extr6mit6 est maintenue dans un plan rigide; ces bornes s'expriment ~ l'aide de la rigidit6 fi la torsion de Saint-Venant, du moment polaire d'inertie de la section et de la valeur propre fondamentale de la membrane libre, ainsi que la longueur du cylindre et des constantes d'61asticit6. Elles peuvent servir ~ d6montrer que ces deux rigidit6s coincident quand la longueur du cylindr6 tend vers l'infini. Nous 6tudions aussi d'autres implications des bornes.
