ANALYSIS OF A THIN AND THICK WALLED PRESSURE VESSEL FOR DIFFERENT MATERIALS

Abstract

In the present work the problem of calculation of the stress developed in the thin and thick cylindrical pressure vessels is numerically solved by using software in C++. The analysis has been done for two different materials pressure vessels. The variations in the thickness of the pressure vessels have been considered for the analysis for different internal pressures. The common characteristic of the pressure vessels solved is that the radial and tangential stresses vary in the same nature of curve for different thickness of vessels. Lame's equations, maximum normal stress theory, maximum shear stress theory have been applied for the analysis of the thick walled pressure vessels of brittle and ductile materials. Analysis also performed for open and closed end cylinders by using Burnie's equation and shear strain theory. Barlow's equation has been applied for the calculation and analysis of the high pressure oil and gas pipe analysis. The yield point stress and ultimate stresses have been considered for the ductile and brittle material respectively. The modeling details of the methodology, employed in the analysis, are extensively discussed and the numerical approach is proven to be very efficient for the software developed of pressure vessel for thin and thick cylinders.
