Electrical Analogue to a Celled Tube Subjected to Flexure and Torsion: A Method of Solution Without Formulating the Structural Equations

Abstract

A new analogue approach is presented for the solution to the multi‐celled, multi‐stringer tube subjected to flexural and torsional loads. This approach is based upon the condition of current continuity and an equivalent to Castigliano's theorem which holds for certain types of electrical networks. The associated equations lend themselves to creating an analogue with a high degree of pictorial similarity, so that the network can be constructed without formulating the structural equations. The analogue of a simple two‐celled structure is devised and the results obtained by electrical circuit analysis are checked against the structure.
