Thin wall cylinder
WebSummary. There are three primary mechanical stresses that can be applied to a spherical or cylindrically shaped object: Hoop Stress. Axial Stress. Radial Stress. If the object/vessel has walls with a thickness less than one-tenth of the overall diameter, then these objects can be assumed to be ‘thin-walled’ and the following equations be ...

WebUnlike thin-walled vessels, thickwalled cylinders do not tend to buckle under excessive external pressure, but merely crush. Tangential Stress Formula: σt = (pir2i - por2o + (pi - po) (r2i r2o / r2)) / ( r2o - r2i ) If the external pressure ( po) is zero gage, meaning atmospheric, then the tangential stress (σt) becomes:
