Abstract: The article presents a method for computing loads (such as strain or torque) on a compound shell consisting of elastically linked external and internal shells for the case when the external shell is subjected to transverse loading (bending moment, shear forces and distributed inertial loads). To demonstrate the application of our method, we investigated the effect the rigidity properties of the external shell have on the internal shell loading.

Keywords: external shell, internal shell, compound shell, bending moment, flexural rigidity, transfer matrix, concentrated load matrix.
