Theoretical and Experimental Collapse Analysis of Ring Stiffened Shells Using Finite Element Software Packages and Application of Results to a Submarine Pressure Hull
It is empirically established that, due to a number of factors involved, a classical (linear) analysis of buckling pressure is impossible. Nonlinear theories of buckling are, therefore, required that involve effective factors such as imperfections and welding effects. In this study, models are developed which are as close to allowable standard deviations as possible. In the next stage, their bu...

متن کاملTechnical Notes on the Near Surface Experiments of Submerged Submarine
In this study, the experimental analysis on the bare hull resistance coefficient of submarine at snorkel depth is represented. The experiments are conducted in marine laboratory of Admiral Makarov University. The results are presented for surface condition and snorkel condition. Snorkel depth is regarded equal to one diameter of submarine hull beneath the water surface as usual in submarines. P...
متن کاملExpert system based on the arrangement evaluation model for the arrangement design of a submarine
The arrangement design of a submarine depends on the past design data and experts’ experiences. Delay in design can occur due to data missing or the absence of experts. In addition, various compartments and equipment are placed on the limited space called pressure hull in the submarine, so that the relation between the compartments and equipment should be considered carefully when designing the...
متن کاملComputation of Turbulent Viscous Flow around Submarine Hull Using Unstructured Grid
This paper presents finite volume method based on Reynolds-averaged Navier-Stokes (RANS) equations for computation of 2D axisymmetric flow around bare submarine hull using unstructured grid. The body used for this purpose is a standard DREA (Defence Research Establishment Atlantic) bare submarine hull. Shear Stress Transport (SST) k-ω model has been used to simulate turbulent flow past the hull...
