Pressure vessels are used for various purposes such as reservoirs and storage vessels of lethal or non-lethal fluids, nuclear reactor, heat exchanger etc. In general, cylindrical vessel is popular as pressure vessel, due to its simple and robust structure. However cylindrical pressure vessel has a limitation of low volume efficiency compared to prismatic pressure vessel. Volume efficiency of cylindrical pressure vessels is approximately 25 ~ 50% lower than that of prismatic pressure vessels. Even though, prismatic pressure vessels enjoy better volumetric efficiency, it is difficult to design, as the developed bending stress is much higher than membrane stress, whereas in cylindrical vessel membrane stress is predominant. In the present work, a pressure vessel made from stiffened panel is designed and analyzed analytically and numerically. An orthotropic plate approach is used to find the stiffness parameters of the stiffened panel. The loading on the plates is determined by the principle of superposition theory. Levy’s method of plate theory is used to solve the governing equations of plates. Along with analytical method, Finite Element Method is also used to study the deformation behavior and stress levels of the prismatic vessels made from stiffened panel. By varying the stiffening properties of the stiffened panels, the response behavior of the prismatic vessel is investigated using both analytical and FEM method. A comparative study of the outcomes of the analytical and FEM method is performed.
