Investigation of Circular, Elliptical and Obround Shaped Vessels by Finite Element Method(FEM) Analysis under Internal Pressure Loading
Abstract
The forms of pressure vessels applicable withinside the aerospace enterprise are starting from essential load-carrying imperative tank systems to small auxiliary tanks and pressurized cabins. Elliptical and obround stress vessels are used in which there may be a space-constrained. In the present work nonlinear(geometric and material within tensile strength) finite element evaluation is performed for the determination of its stress state in open-ended pressure vessels of various shapes(round, elliptical, and obround). A parametric examine has been completed and outcomes offered for different inside areas of vessel shapes and thickness of the cross-sections. As the inside area of the shape of pressure vessel increases, the effective stress increases for a particular thickness. The deformed shape elliptical/obround under internal pressure might no longer be uniformly enlarged because of non-uniform bending. Deformation and effective stress in the elliptical/obround shapes are found higher than circular shape for a particular thickness and inside area of vessel.
