“…This is because in contrast to ASME BPVC-X, NASA SP-8007 requires a longitudinal/circumferential wave number of buckling The FE results match well against the experimental data of Section 2.2.2. This is also confirmed in several references [7][8][9][10]12,14]. Based on these comparisons, the accuracy of design codes for the prediction of collapse strength could be considered insufficient.…”

“…Farooq and Myler [25] confirmed that effective engineering constants obtained from various equations have shown a good agreement (over 90%) between laminates having different types of stacking sequences by performing tensile and bending tests. Jung et al [12] compared the buckling pressure obtained from FE analysis for different stacking and effective material properties. They concluded that a single layer with effective engineering constants is adequate.…”

Submarine hulls are pressure vessels for which excellent structural integrity under underwater pressure loads is essential. The use of light-weight materials contributes to reduced fuel consumption, improved speed, and increased payload while strength properties are retained. The focus of this paper is on the collapse behavior of a filament-wound cylindrical structure that serves as the main hull of a submarine subject to hydrostatic pressure loads. This paper presents a computational modelling approach for the prediction of the collapse behavior mechanism using a commercial finite element (FE) solver. The collapse strength obtained from the numerical model corresponded closely to available experimental data. The composite and aluminum material models were compared and the effects of stacking angle and thickness portion in the ply sequence on collapse strength were investigated. The advantages and disadvantages of available design codes (i.e., American Society of Mechanical Engineers (ASME) BPVC-X and National Aeronautics and Space Administration (NASA) SP-8007) were reviewed by direct comparison with numerical results. It is concluded that the application of effective engineering constants for the prediction of the collapse pressure of submarine hulls may be feasible.

“…The results showed that the failure pressure of the reinforced composite cylindrical shell was much higher than the unreinforced one, and the buckling pressure of the cylindrical shell with the winding angle of [±60 • /90 • ] was the largest. Jung et al [46] selected several groups of different winding angles, such as [±30 ] FW , to conduct finite element analysis and comparative analysis of buckling criteria for the buckling characteristics of wound composite cylindrical shells under external hydrostatic pressure. It was found that the buckling pressure calculated by the ASME 2007 formula had the highest safety factor compared with the test value, and the finite element results were in good agreement with the test value.…”

With the increasing application and study of lightweight and high strength fiber reinforced polymer composites in ocean industry, the structural failure problem of composite pressure hulls has attracted great attention from many researchers in China and globally. Analysis of the structural failure mechanisms is foundational to the design of deep-sea composite pressure hulls, since nowadays the design rules of pressurized vessels is mostly formulated according to their failure modes. Hence, this paper aims to review the research on the structural failure of composite pressure hulls in deep sea settings. First of all, the applied research status on composite material in marine equipment is analyzed, including inspection modalities for composite pressure hulls. The review then focuses on the three main failure modes, namely overall buckling, material failure and snap buckling of the deep-sea composite pressure hulls. The study identifies further problems of composite pressure hulls to be solved through the application of the deep sea equipment research, aiming to provide a reference for the study of mechanical behavior, ultimate strength computation, and design of thick composite pressure hulls for deep sea equipment.

“…Messager et al (2002) later developed an analytical buckling shell model based on third-order shear deformable theory and compared the results with NLFEM and experimental results. Kim et al (2010) and Jung et al (2012) compared two analytical buckling pressure formulations, i.e., the ASME and NASA formulas, with NLFEM or experimental results. Rao Yarrapragada et al (2012) used the Windenburg equation, which was developed for homogeneous materials, to predict the critical buckling pressure of composite shells with equivalent stiffness moduli, and compared the results with NLFEM.…”

This paper derives an empirical formula for predicting the collapse strength of composite cylindrical-shell structures under external hydrostatic pressure loads as a function of geometric dimensions and layered angles, where the effects of initial manufacturing imperfections are implicitly taken into account. A series of experiments are undertaken on [ /90]FW filament-wound-type composite cylindrical-shell models subjected to collapse pressure loads. A total of 20 composite cylindrical-shell models are tested to derive the empirical formula, which is validated by comparison with experimental data, existing design formulas of ASME 2007 and NASA SP-8700, and solutions of the nonlinear finite element method. It is concluded that the proposed formula accurately predicts the collapse pressure loads of filament-wound composite cylinders and will thus aid the safety design of composite cylindrical shell-structures under external pressure loads.
