TLDR
In this article, the effect of various geometric and material properties on natural frequencies of stiffened shells are investigated using two approaches: (i) with a discontinuous radius of curvature, i.e., the radius of curve varies in steps and (ii) continuous, but eccentric thickness.About:

A modified variational approach for vibration analysis of ring-stiffened conical–cylindrical shell combinations
TL;DR: In this article, a modified variational method for dynamic analysis of ring-stiffened conical-cylindrical shells subjected to different boundary conditions is presented, which involves partitioning the stiffened shell into appropriate shell segments in order to accommodate the computing requirement of high-order vibration modes and responses.

Free vibration analysis of joined cross-ply laminated conical shells
TL;DR: In this article, the vibrational behavior of two joined cross-ply laminated conical shells is investigated and the natural frequencies and mode shapes are investigated, assuming trigonometric response in circumferential and series solution in meridional directions.

Free vibration of joined conical-cylindrical shells
T. Irie,Gen Yamada,Y. Muramoto +2 more
TL;DR: In this paper, the free vibration analysis of joined conical-cylindrical shells is presented, where the governing equations of vibration of a conical shell, including a cylindrical shell as a special case, are written as a coupled set of first order differential equations by using the transfer matrix of the shell.

TL;DR: In this paper, the finite element method was used to investigate the natural frequencies and mode shapes of thin circular cylindrical shells with stiffening rings, where each stiffening ring was treated as a discrete element.
