Abstract
Pressure hulls are designed to stand the hydro static and dynamic bearing when they operate under water. These structures are also applied to naval submarines, remotely operated vehicle (ROV) and autonomous underwater vehicles (AUV). The underwater vehicle plays an important role in the petroleum industry, ocean engineering, and fishing, etc. To do so, ROV and AUV are studied for design and fabrication. This paper focuses on studying linear and nonlinear buckling analysis of stiffened cylindrical pressure hull under bearing load in Vietnam sea environment. The modeling of this pressure hull structure has been carried out by finite element analysis software packages.

AT The buckling strength of ship and offshore structures are always an important part in design and analysis procedures
The classical buckling strength of shell under axial compression is based on Timoshenko and continues to be studied in numerical and experimental model reference loads for the cylindrical shell [1]
In order to determine the converge of good results for the finite element analysis, the model is divided with three strategies of meshing, the Lmesh size of 50mm, 75 and 100mm, the ultimate strength of the cylindrical under axial compressed load with hydrostatic pressure p = 1.1772 MPa, the obtained results are: 284.688 MPa, 284.984 MPa and 285.2429 Mpa in Figure 12 and 13, respectively
Summary
AT The buckling strength of ship and offshore structures are always an important part in design and analysis procedures. The classical buckling strength of shell under axial compression is based on Timoshenko and continues to be studied in numerical and experimental model reference loads for the cylindrical shell [1]. The buckling strength of shell under hydrostatic pressure is studied, for convenience, Warren C.Young and Richard G.Budynas provide a handbook to rapidly calculate for the various problem of solid structures [2]. This method helps designers can estimate the linear buckling behavior without needing numerical analysis. Guedes Soares make an assessment of five narrow stiffened panels tested with two stiffeners under axial compression until collapse and beyond is determined by finite element analysis, and is compared with experimental results [4]
