Thick walled hoop stress
WebThe allowable hoop stress is the critical hoop stress divided by the safety factor which was hardened in the 11th edition to become 1.5 for extreme conditions and 2.0 for other conditions. Hope buckling stress is calculated in Eq. (3.91). In the 11lth edition, in 1980, the critical hoop buckling stress was defined as follows: (7.10) (7.11) (7. ...
