“…It contributes about one-fourth to one-half of the total underwater vehicle weight. Figure 1 presents various pressure hull configurations used in submersible bodies [26][27][28]. Exposing the hull structure to shock wave and bubble pulsation upon UNDEX events leads to great damage to the hull structure [2].…”

Among the most important problems confronted by designers of submarines is to minimize the weight, increase the payload, and enhance the strength of pressure hull in order to sustain the hydrostatic pressure and underwater explosions (UNDEX). In this study, a Multiple Intersecting Cross Elliptical Pressure Hull (MICEPH) subjected to hydrostatic pressure was first optimized to increase the payload according to the design requirements. Thereafter, according to the optimum design results, a numerical analysis for the fluid structure interaction (FSI) phenomena and UNDEX were implemented using nonlinear finite element code ABAQUS/Explicit. The propagation of shock waves through the MICEPH was analyzed and the response modes (breathing, accordion and whipping) were discussed. Furthermore, the acceleration, displacement and failure index time histories at different locations were presented. The results showed that the greatest acceleration occurred in the athwart direction, followed by the vertical and longitudinal directions. Additionally, the first bubble pulse has a major effect on athwart acceleration. Moreover, the analysis can be effectively used to predict and calculate the failure indices of pressure hull. Additionally, it provides an efficient method that reasonably captures the dynamic response of a pressure hull subjected to UNDEX.

“…A comprehensive effort has been made by Smith (1991), Smith et al (1991), Liang et al (2003) and Lee et al (2013) to examine the use of fibre-reinforced polymer composites and sandwich construction in the pressure hulls of submersible vehicles. Sandwich shells are also gaining wide spread acceptance as primary load bearing members in aerospace structures, automobile bodies, subsea applications, naval ship components and wind turbines.…”

The paper focuses on the analysis of sandwich domes using a newly developed doubly curved axisymmetric sandwich finite element. The simple equivalent single layer finite element employs a cubic polynomial approximation for transverse displacement and meridional displacement. The present element accounts for the transverse shear strains of the facing and core using quadratic polynomial. The relation between inplane stresses and strains for axisymmetric deformation has been represented by a state of generalized plane stress. The stiffness matrix has been derived using the variational principle. The numerical examples have been presented to illustrate the element capabilities and accuracy of the results achieved using the newly developed sandwich shell element.

“…This is a good structure to resist the effects of external hydrostatic pressure [39]. Figure 3 shows various wall architectures used for pressure hulls which include pure monocoque constructions, gas-storage toroidal tube-stiffener hull wall construction, traditional ring-stiffened hull wall constructions, trapezoid corrugated hull wall construction, ring-stiffened corrugated pressure hull wall construction, and sandwich hull wall construction [7,18]. In this study, an elliptical pressure hull as shown in Figure 1 is proposed for a better space utilization, good hydrodynamic form, and stability; this is better than a spherical form of the same volume and is easy to manufacture.…”

“…A submarine designer pointed out that the safety factor of 1.5-2.0 is considered acceptable in most engineering practice [6]. Liang et al [7,8] optimized the design of filament-wound multilayer sandwich submersible pressure hulls. The facings become thicker and the core becomes thinner as the operational depth increases.…”

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 influence of the design variables on the structural optimum design. Results of this study provide a valuable reference for designers of underwater vehicles.
