Axisymmetric Analysis of Internally Pressurized Rotating Cylinder Using FEM Under Thermal Environment

Abstract

The work done under this project is based on mathematical approach for analyzing stress of a homogeneous,isotropic, internally pressurized rotating cylinder under thermal conditions.The equations of importance for this analysis have been derived by using the general stress equilibrium, Kirchhoff’s law of heat conduction and Newton’s law of force equilibrium.The finite element method will be used to find out the stresses and displacements at each node of isoparametric elements (bilinear).FEM results so obtained will be then compared with the results from analysis using ANSYS.The reason for doing comparison is to have an idea about the variance in the results of FEM by analytical method from the approximate solution obtained from ANSYS analysis and to see the extent up to which the results of FEM meet the accurate values by increasing the number of elements.
