7.3 The Thin-walled Pressure Vessel Theory

homepages.engineering.auckland.ac.nz

A thin-walled spherical shell is shown in Fig. 7.3.3. Because of the symmetry of the sphere and of the pressure loading, the circumferential (or tangential or hoop) stress t at any location and in any tangential orientation must be the same (and there will be zero shear stresses). Figure 7.3.3: a thin-walled spherical pressure vessel

Thin Walled Pressure vessels. The cylindrical pressure vessel above has closed ends and contains a fluid at gauge pressure P as shown below. The outer diameter is D and the wall thickness is t. The term ‘thin-wall’ may be taken to mean that D/t > 10. D t Fluid at pressure P. L P

A pressure vessel is considered as any closed vessel that is capable of storing a pressurized fluid, either internal or external pressure, regardless of their shape and dimensions. The cylindrical vessels, to which we refer in this volume, are calculated on the principles of thin-walled cylinders.

found in thick walled cylindrical pressure vessels. In the most general case the vessel is subject to both internal and external pressures. Most vessels also have closed ends - this results in an axial stress component. Principal stresses at radius r : And, if the ends are closed, 2 2 2 σ1 =σθ=−K +C/r: σ=σr =−K +C/r σ3 =σaxial =−K ...

Vessel members ar e inter connected thr ough per forations in their common walls. The presence of vessels is a characteristic feature of angiosperms. Xylem fibres have highly thickened walls and obliterated central lumens. These may either be septate or aseptate. Xylem parenchyma cells are living and thin-walled,
