The equivalent circuits of shells used in airframe construction

Abstract

In discussing elastic shells one must be careful to state clearly the type of shell being discussed. Although a complete description together with restrictive assumptions will be given later, it is well to state at the outset that the type of shell discussed in this paper is the type to be found in aircraft fuselage construction. Such a shell has an elongated shape and consists of a thin skin supported by rings and longitudinal members. In analyzing such shells it is the universal practice to replace the elastic supporting rings by rigid bulkheads in order to simplify the analysis. This assumption will not be made in this paper.
