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.

TL;DR: In this paper, the free vibration characteristics of conical-cylindrical-spherical shell combinations with ring stiffeners are investigated by using a modified variational method, where the displacement fields of each shell segment are expressed as a product of orthogonal polynomials along the meridional direction and Fourier series along the circumferential direction.

TL;DR: In this paper, a domain decomposition technique for solving vibration problems of uniform and stepped cylindrical shells with arbitrary boundary conditions is presented, where the displacement components of each shell domain are expanded in the form of a double mixed series: Fourier series for the circumferential variable and polynomials/series for the axial variable.

TL;DR: In this paper, a variational method is proposed to study the free vibration of joined cylindrical-conical shells (JCCSs) subjected to classical and non-classical boundary conditions.

TL;DR: In this paper, a series of comparative tests were carried out to comprehend the dynamic performance of a layer of rubber sandwich with the square honeycomb core coated onto ship hull and the results showed that the protective rubber layer is capable of moderating damage of the ship body caused by shock wave while not very effective in reducing the whipping damage excited by bubble pulse.
