The Rayleigh theory of inextensibility is used to predict the displacement behaviour of a thin-walled cylindrical shell subject to a static couple. The effect of the position of load application is investigated. Characteristic curves are presented for a series of load positions for constant shell dimensions, together with curves showing the effect of different shell sizes. Experimental verification of the theory is provided, tests being performed on a cylinder in which the loads are applied at the ends of a diameter. Satisfactory correlation was found between the experimental and theoretical results.
