In this investigation the general frequency equation for trains of harmonic waves having an arbitrary number of circumferential nodes, traveling in orthotropic circular cylindrical shells is established on the basis of the three-dimensional linear theory of elasticity, by expanding the displacement components in power series of the radial coordinate. Simpler forms of the frequency equation for axisymmetric nontorsional and torsional motion and for longitudinal-shear and plane strain motion are established and discussed. Author
