7.3 The Thin-walled Pressure Vessel Theory - Auckland
pkel015.connect.amazon.auckland.ac.nzA 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
CHAPTER 3 PRESSURE AND FLUID STATICS
www.et.byu.eduAnalysis Atmospheric air pressure which is the external pressure exerted on the skin decreases with increasing elevation. Therefore, the pressure is lower at higher elevations. As a result, the difference between the blood pressure in the veins and the air pressure outside increases. This pressure imbalance may cause some thin-walled veins such

Calculate the stress in a thin walled sphere 100 mm mean diameter with a wall 2 mm thick when the outside pressure is 2 MPa greater than the inside. (Answer -25 MPa).
Thick Walled Cylinders - University of Washington
