Note that the formula for hoop stress from thin walled theory is p(ID)/2t, while from thick walled theory it is p[(L2 + 1)/(L2 - 1)] where t is the wall thickness of the pipe and L is the ratio OD/ID. Which formula would you use and why?

A design chart recommended by the resin suppliers or interference formula can be used to design a press-fit joint at a desirable stress, so the parts will not crack because of excessive stress or loosen because of ... The design should not cause the hoop stress, , to exceed the proportional limit of the material.

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. ... That formula (I have Roark's sitting in front of me) is for relatively long,

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.

Since the outer wall of a standard double-wall pipe has a diameter larger than that of the inner wall, the outer wall will experience hoop stresses of higher magnitude than the inner pipe for a given working pressure. ... Further, no permeable stress-resisting structure is provided between the impermeable inner and outer walls.
