The present research was aimed at comparing performance of metallic and polymer composite shells of a typical underwater vessel of length and inner diameter of 1650 mm and 350 mm respectively, based on the critical buckling pressure for operating depth of 1000 m using ANSYS. High strength steel, aluminium alloy, titanium alloy, glass / epoxy and carbon / epoxy materials were examined. The results indicated weight savings of 46 % in carbon/epoxy and 31 % in glass / epoxy when compared with high strength steel, based on the thickness of the shell for sustaining 10 MPa buckling pressure.

“…A circular cylindrical hull is a good shape to resist the pressure (Ross, 2006). Many of the current AUVs have a circular cylindrical hull including the most popular in military and scientific use, the REMUS100 (Hsu et al, 2005;Evans & Meyer, 2004;Maurya et al, 2007).…”

“…In the past, the most used material was steel. In (Ross, 2006) four materials are compared; high strength steel, aluminium, titanium and composites. The advantages of high strength steel are the price and the fact that it is commonly used, so there is much knowledge of it.…”

Abstract.Composite is used to substitute aluminum alloy as material of the underwater vehicle in this study. Nonlinear buckling behaviors of composite cylindrical underwater shell are studied using ANSYS software. Carbon/Epoxy is selected as material of the vehicle through comparative analysis. Optimization of ply sequence, thickness and angle of composite cylindrical shell subjected to hydrostatic pressure is investigated. Both buckling and material damage is considered in the optimization, the results show that buckling is the major destroy form. The vehicle's buckling pressure is greatly increased after optimization. And the vehicle's working depth has a 32% increase without changing its shape and structure.
