“…7). It is to be noted that as D 11 is equated to arrive at the properties of the equivalent cylinder having the same bending stiffness, D 16 and D 26 and all the A terms of the equivalent cylinder are different from the given cylinder and they cause significant difference in the results. These results signify the need for the expression derived in this work.…”

Vibration and noise radiation from fluid-loaded cylindrical shells are controlled using multiple stiffeners and Passive Constrained Layer Damping treatment. Dynamic and fluid finite element models are developed to study the fundamental phenomena governing the interaction between the stiffened shell, with and without damping, and the fluid domain surrounding it. The models are used to predict the response of the shell and to evaluate the effect of the stiffening rings and damping treatment on both the structural vibration and noise radiation in the fluid domain. The prediction of the models are validated experimentally and against the predictions of a commercial FE software package (ANSYS). It is shown that stiffening of the shell reduces the amplitude of the vibration and noise radiation, particularly for high order lobar modes. The attenuation of the shell response and sound radiation can be significantly increased through the application of Passive Constrained Layer Damping treatment on the inner surface of the stiffening rings. The numerical and experimental validations demonstrate the accuracy of the developed models and emphasize its potential extension to the application of smart materials for active control of vibration and noise radiation from fluid-loaded shells.

“…Finite element free vibration analysis of stiffened composite shells is also studied by Nayak and Bandyopadhyay [16], Li et al [17], Rikards et al [18], etc. The work of Bert et al [19] used the five different thin shell theories and analytical approach determined the natural frequencies of laminated composite circular cylindrical shell stiffened by the ring and/or stringer stiffeners.…”

In this paper, the analytical solution for the cross-ply laminated composite double curved shell panels with stiffeners is presented. Based on the smeared stiffeners technique and the first shear deformation theory (FSDT), the motion equations are derived by applying the Hamilton’s principle. The Navier’s solution for the simply supported boundary condition for all edges is presented. The numerical results are veriﬁed with the known results in the literature. The effects of the number of stiffeners, dimensions of stiffeners, and lamination scheme of cross-ply laminated composite doubly curved shell panels on the natural fundamental frequencies are investigated.
