Abstract: The behavior of material subjected to thermo mechanical loads is of interest to researchers in a wide variety of discipline. Axi symmetric pressure vessels have wide use in industrial engineering. They often operate under combined mechanical and thermal loads which may be constant or cycling. The combined effects of temperature and pressure must be taken into account when designing cylinders. Cylinders have wide application in chemical, petroleum and military industry. Various methods of prestressing techniques such as compound cylinder, increasing wall thickness are used so that thick cylinders can resist large internal pressure and to make effective use of material at the upper portion of the cylinder. In this thesis work the analytical and numerical analysis of compound thick cylinder is given. The evaluation of the resistance and the conformity of the cylinders depending upon the conditions of use are illustrated by stress and displacement distributions. The results of the analytical approach are validated to a finite element model.
