Purpose of Calculation
Calculation of stresses in rotating Disks and Rings resulting from Internal and external pressures
Calculation of torque transmitted by interference fit
The various calculations have been checked against example in above texts. The theoretical derivation of the equations is found on the above website.

This page includes simple equations for calulating the longitudonal ,tangential and radial stresses in thick cylinders with closed ends. It should be noted that material stress units are based on tensile forces = +ve and compressive forces= -ve. Therefore the pressure on the surface which niput as a positive value results in an equal but opposite radial stress within the local surface.
1) Pressurised Thick CylinderRadial /Tangential stresses
2) Pressurised Thick CylinderLongitudonal stresses for a thick walled cylinder with closed ends
3) Calculation of Interface Pressure resulting from an Interference fit
