In this paper; a submarine vessel’s shell element’sdeformation has been investigated due to hydrotatic pressure. Eleven differentpressure value for eleven depth has been accounted. A doubly curved shellelement within different radius and different lenghts of edges is analysed byusing numerical method solution of static linear equilibrium equation of shellelement. In the solution part, Navier Solution method with double Fourierseries is used for solution of final differantial equations. Identical shellelement has been analysed in a package program ANSYSTM in order to verificationof solution. Following of verification, cylindrical shell element has beenanalysed with numerical method. In numerical analysis a MATLABTM code iswritten for easy solution for different curvature radiuses and differentlenghts of edges. After all solution analyses, stres components of shellelements has been compared with Turkis Loyd permitted stress components fordesign of a submarine. As a result, it’s studied on deformation of isotropicshell element according to different length-thickness ratio and length values.
