Influence of boss size on the stress distribution in the material is always taken into account for the failure analysis of metallic structures. In this investigation, the effect of round shaped through holes in the turbojet turbine case on the stress distribution under uniform pressure is carried out using Ansys Workbench software. Two types of steel, namely mild steel and high carbon steel with thickness of cylinder 0.8, 1.0, 1.25 and 1.5 mm were considered independently. Also considered are, cylinder with and without bosses under 5 and 7.5 bar pressure separately. Von Mises stress values so obtained are tabulated for comparision. Presence of bosses introduce more stress in the cylinder than that for cylinder without bosses. Effect of thickness of cylinder on the Von mises stress distribution is observed in both the materials. FEM result is matching with the calculated classical mechanics result with 2 to 4% error approximately.
