7.3 The Thin-walled Pressure Vessel Theory

7.3.2 Thin Walled Cylinders The analysis of a thin-walled internally-pressurised cylindrical vessel is similar to that of the spherical vessel. The main difference is that the cylinder has three different principal stress values, the circumferential stress, the radial stress, and the longitudinal stress l,

using only force equilibrium considerations as was done for the thin walled cylinder. The result is then simply superimposed on the above equations. The pressure P i acts on area given by πr i 2. The pressure P o acts on area given by πr o 2. The axial stress σ z acts on an area given by π(r o 2 –r i 2) Force equilibrium then gives: −
