An Extension of the Validity of Beam Theory Beyond its Classical Bounds

The elementary beam theory for shell structures yields the exact solution for normal and shear stress, if the three following conditions are fulfilled: (a) the shell must be prismatic; (b) the cross section must not deform in its plane; (c) the centres of rotation of the different cross sections must form an axis of rotation parallel to the longitudinal axis of the beam.
