Abstract
This paper is concerned with stiffened plating to which a bending moment is applied in the plane of the stiffener webs. Owing to the initial or imposed curvature there is a radial component of force which tends to deflect the plating from its original position, and the effects of this deflexion may be considerable. There is a change in the distribution of longitudinal stress across the plate, and a transverse bending stress is induced which may exceed the longitudinal stress. The effects of initial deflexion of the plating, and of lateral load, are also considered.
A numerical example illustrates the application of the analysis to the transverse bending of a ship's side. An experiment is described which confirms the theoretical conclusions for an initially flat plate.
