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.

“…Cai [13] presented a design procedure and calculated the buckling pressure of composite pressure shells subjected to external hydrostatic pressure based on the classical laminate theory. With the improvement of computer performance, finite element analysis has become an effective method to evaluate buckling failure of composite structures [14][15][16][17]. Mohammad [18] employed a triangular shell element having six nodes to investigate the nonlinear behavior of cylindrical shells with irregular mesh and complicated geometry, where total Lagrangian formulation was utilized considering the large deflection and rotation.…”

In this paper, the buckling and post-buckling behavior of perfect and perforated composite cylindrical shells subjected to external hydrostatic pressure was experimentally investigated. Three filament wound composite cylindrical shells were fabricated from T700-12K Carbon fiber/Epoxy, two of which were perforated and reinforced. A test platform was established that allows researchers to observe the deformation of composite cylindrical shells under hydrostatic pressure in real-time during test. According to experimental observation, strain response and buckling deformation wave were discussed. Comparative analysis was carried out based on the experimental observation and finite element prediction. Results show that the deformation of composite cylindrical shell under hydrostatic pressure included linear compression, buckling and post-buckling processes. The buckling behavior was a progressive evolution process which accounted for 20% of the load history, and strain reversal phenomenon generally occurred at the trough of the buckling wave. As for the postbuckling deformation, the load carrying capacity of the shell gradually decreased while the magnitude of strain continued increasing. Both the perfect and perforated composite cylindrical shells collapsed at the trough of the buckling wave. Comparing with the perfect shell, it was validated the reinforcement design could effectively ensure the load carrying capacity of the perforated composite cylindrical shell.

“…Similar shell finite elements were used by Ram and Babu (2002), and Barbosa and Ferreira (2009), Bakshi and Chakravorty (2014). ANSYS shell element "Shell 99" is a similar shell element ,which can be used for stability analysis of thin-walled composite structures; see, for example Öner et al (2007) and Shen et al (2017).…”

In this study, the influence of pressure stiffness on the torsional buckling of thin and moderately thick laminated composite perfect cylinders under external hydrostatic pressure is investigated. A degenerated-curved shell element is used to obtain the numerical results. First, a verification problem is solved and the element is validated for stability analysis including pressure stiffness. Then, cross-ply and angle-ply laminated composite cylinders are examined for selected lengthradius ratios and stacking sequences. The results obtained show that, pressure stiffness may have a stabilizing effect against torsional buckling especially for thick orthotropic cylinders.
