Pressure vessels are widely used in many industrial applications. Openings provided in pressure vessels are very common, they may be of different sizes and shapes and may also be at different locations and inclinations as the need may be. The pressure vessels are usually subjected to high pressures and temperatures which may be constant or cycling. In the present study a parametric stress analysis is conducted on a thick walled cylinder subjected to constant internal pressure. The parameters varied are the thickness ratio (k), crosshole radius ratio (d) and crosshole angle (α). The Finite Element Analysis is conducted using commercial solver ANSYS Workbench in determining the stress components of the cylinder and the equivalent (von-Mises) Stress distributions for different crosshole radius ratios and crosshole angles. The variation of the stress concentration factor and the maximum failure pressure in each case is recorded and tabulated. The results and conclusions are presented in form of graphs and tables.
