TL;DR: In this article, the authors investigated the optimum design of a composite elliptical deep-submerged pressure hull under hydrostatic pressure to minimize the buoyancy factor of the submersible pressure hull with constraints on the failure criteria and the buckling strength of the hulls.
Abstract: The design of deep submersible pressure hull's structural is one of the core technologies of submersible development of human history. Submersible pressure hulls with fiber-reinforced multilayer constructions have been developed in the recent years as substitutes for classical metallic ring-stiffened pressure hulls; strength and stability are its top priority. This paper investigates the optimum design of a composite elliptical deep-submerged pressure hull under hydrostatic pressure to minimize the buoyancy factor of the submersible pressure hull under constraints on the failure criteria and the buckling strength of the hulls to reach the maximum operating depth. The thickness and the fiber orientation angles in each layer, the radii of the ellipse, and stringers dimensions were taken as design variables and determined in the design process. The optimization procedures are performed using commercial finite element analysis software ANSYS. Additionally, a sensitivity analysis is performed to study the infl...

TL;DR: In this paper, the test methods recommended in these data sheets apply to resin matrix composites reinforced with orientated continuous fibres and are valid for all grades of carbon glass and aramid fibres, in both U/D tape and woven fabric forms.
Abstract: : The test methods recommended in these data sheets apply to resin matrix composites reinforced with orientated continuous fibres. They are valid for all grades of carbon glass and aramid fibres, in both U/D tape and woven fabric forms including mixed fibre hybrid combinations, provided that the modes of failure are representative. Epoxy resin matrix systems were used in the development of these methods, but, although confirmatory test evidence is lacking, other resin systems should be equally suitable provided that the composite properties fall within any prescribed test limitations and that valid failure modes are obtained. All multidirectional laminates, including woven fabric laminates, must have their ply orientations and stacking sequence balanced about the mid-plane and the longitudinal axis to ensure axial loading and to prevent rotational, flexural, or off-axis displacements.

TL;DR: In this article, numerical solutions have been produced for the asymmetric instability of thin-walled circular cylindrical and truncated conical shells under external pressure, which can be applied to vessels of varying thickness or those subjected to unsymmetrical loading or with complex boundary conditions.
Abstract: Numerical solutions have been produced for the asymmetric instability of thin-walled circular cylindrical and truncated conical shells under external pressure. The solutions for the circular cylinder have shown that the assumed buckling configurations of Nash and Kaminsky were quite reasonable for fixed ends. Comparison was also made of the finite-element solution of conical shells with other analyses. From these calculations, it was shown that the numerical solutions were superior to the analytical ones, as the former could be readily applied to vessels of varying thickness or those subjected to unsymmetrical loading or with complex boundary conditions.
