A one-dimensional model endowed with an energy that generalizes Sadowsky's is used to study ribbons subjected to a combination of traction and twist and to fully characterize the set of equilibrium configurations having constant curvatures. A stability analysis for the helicoidal configuration identifies a critical point at which spiral configurations branch out. A stability analysis then shows that the part of the helicoidal branch corresponding to tractions larger than the value identifying the critical point is stable.

Abstract
A one-dimensional model endowed with an energy that generalizes Sadowsky's is used to study ribbons subjected to a combination of traction and twist and to fully characterize the set of equilibrium configurations having constant curvatures. A stability analysis for the helicoidal configuration identifies a critical point at which spiral configurations branch out. A stability analysis then shows that the part of the helicoidal branch corresponding to tractions larger than the value identifying the critical point is stable.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
