Stress analysis of thick walled cylinder

Abstract

It is proposed to conduct stress analysis of thick walled cylinder and composite tubes(Shrink fits) subjected to internal and external pressure. Many problems of practical importance are concerned with solids of revolution which are deformed symmetrically with respect to the axis of revolution .The examples of such solids are :circular cylinders subjected to uniform external and internal pressure. The stress analysis of thick walled cylinders with variable internal and external pressure is predicted from lame’s formulae. Different case in lame’s formula are thick walled cylinder having both (a) External and Internal pressure (b) Only Internal Pressure (c)Only External Pressure. In case of Composite tubes (Shrink Fit) the contact pressure between the two cylinders is determined then stress analysis is done by applying external and internal pressure in tube by lame’s formulae. Theoretical formulae based results are obtained from MATLAB programs. The results are represented in form of graphs.
