I am trying to find and equation or algorithm for calculating hoop stress for a short section of thick walled cylinder. The standard formulas for calculating stresses assume a relatively long cylinder, which is not the case in my application.

Circumferential stress in a cylindrically shaped part as a result of internal or external pressure is called as Hoop stress. Hoop stress is mechanical stress defined for rotationally-symmetric obje...

With this choice of axisymmetric coordinates, there is no shear stress. The hoop stress sh and the longitudinal stress sl are the principal stresses. ... To determine the hoop stress sh, we make a cut along the longitudinal axis and construct a small slice as illustrated on the right.

The equation above for hoop stress in a thick cylinder indicates that its value at the inner wall is 4.01p, i.e. 160.4 MPa, and to get the total applied stress intensity factor we need to add in the internal pressure (which loads the crack surfaces).

The predicted lives with and without hoop stress were compared with experimental endurance results obtained at 12 000 and 25 000 rpm with the 120-mm-bore ball bearing. A life factor equation based on hoop stress is presented.

the circumferential or hoop stress σθ (that is σt of cylinder theory) and ... These stresses are graphed for a = 2b, the most common proportions for practical ellipsoidal ends. The prominent feature of this stress pattern is the tensile- to- compressive transition of the hoop stress at about 80%D.

The design should not cause the hoop stress, , to exceed the proportional limit of the material. ... The stress on the interference rings (see the equation above) during ejection must be within the proportional limit of the material at the ejection temperature. The strength at the elevated temperature expected at...

of Mechanical Engineering, London, U.K., 1983The object of this project was to apply the Boundary Integral Equation(BIE) method to the problem of an externally cracked thick walled cylinder subject to internal pressure.In order to do so boundary element meshes were constructed for various values of the relative crack depth,

I'm working on a hoop stress equation for a fabric water tank and kept getting crazy answers from HS=PD/2t so I went on line to check my numbers and noticed that every web calculator I could find used P=rh to calculate pressure, even if the P=rgh equation was listed right next to the calculator.
