Abstract :
A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. Large pressure vessels were invented during the industrial revolution, to be used as boilers for making steam to drive steam engines. Design and testing standards and a system of certification came about as the result of fatal boiler explosions. Pressure vessels can theoretically be almost any shape, but shapes made of sections of spheres, cylinders, and cones are usually employed. A common design is a cylinder with end caps called heads. Head shapes are frequently either hemispherical or dished (torispherical). More complicated shapes have historically been much harder to analyze for safe operation and are usually far more difficult to construct. Theoretically, a spherical pressure vessel has approximately twice the strength of a cylindrical pressure vessel with the same wall thickness. However, a spherical shape is difficult to manufacture, and therefore more expensive, so most pressure vessels are cylindrical with 2:1 semi-elliptical heads or end caps on each end. Smaller pressure vessels are assembled from a pipe and two covers. In this paper, 3D model of pressure vessel has been simulated by finite element method to study the Deformation of vesel, Distribution of stress, Shear and Mises stress contours, Distribution of spatial displacement contours and Contour of equivalent plastic strain in simulation.
