Relation of Hoop and Compressive (Tensile) Stress

[sotree]

Greetings all,

Is there any relation between hoop stress and compressive (or tensile) stress?
Specifically, can hoop stress be derived from the aforementioned stresses?


Thanks

Hoop stress is another name for circumferential stress in tension in a cylinder.

sotree,
There is a relationship bewtween longitudinal and latitudinal (hoop) loads. It involves pressure and the radii of curvatures too.

codeeng,
Hoop stress also exists in cones, spheres, shapes of double curvature. And lots of other shapes I'm sure.

Circular shapes then. How does that sound.

Yes- Hoop stress can be either tensile or compressive, depending on the load (internal or external pressure). But your question is far too vague to get any more specific than that.

sotree ,
If I uderstand you well, you are asking of axial tensile strength and hoop(circumferential) stress in a cylendrical vessel under internal pressure, If it is so, a simple relationshinp exist-

hoop stress = 2*axial stress (tensile)

You can find derivation in mechanics book
