【 摘 要 】

Pressure hulls are the main load bearing structures of naval submarines, and autonomous underwater vehicles (AUVs). A pressure hull is a structure that is designed to withstand the compressive forces associated with hydrostatic pressure. The most efficient geometries for resisting these compressive forces are circular cross-sections, and thus, pressure hulls are typically composed of a combination of ring-stiffened cylinders and cones, with spherical or torispherical domes at either end. The design and manufacturing process of a pressure hull is a cumbersome engineering challenge because of the extreme pressure conditions and extremely low tolerances required. Now a days Burst effect in cylindrical components form a worst loss in manufacturing sector. Burst effect is a failure condition which occurs a cylindrical components subjected to huge amount of internal pressure (Radial stresses). Reduction of Burst effect is a best solution for making safe pressure hull under huge amount of radial pressure condition. Burst effect depends on hoop and longitudinal stress formed. Theses stresses can optimized by variation of thickness of pressure hull and types of materials used for pressure hull.
