Extract

The object of this paper is to contribute one step toward the knowledge of the stresses in the neighbourhood of openings in monocoque aircraft fuselages by developing a procedure for the calculation of the stresses in spaced-curved rings used for reinforcing the edges of openings. The general appearance of such an opening is shown in the perspective view of Fig. 1. The procedure presented here presupposes a knowledge of the forces which act upon the ring. These forces depend upon the relative distortions of the reinforcing ring and of the rest of the fuselage, and the exact determination of their magnitude under different conditions of loading of the fuselage presents great difficulties.
