Problem:

The hoop stress uses the D/t ratio to decide which formula to use, thin or thick, However which is being used in combined stress equation, does the D/t ratio still apply for the hoop stress values used in the combined equation?

Solution:

D/t ratio is used to decide hoop stress formula to be used in combined stress equation. A good discussion on a similar issue is available in our Pipe Stress Analysis Forum which can be accessed by the link below:
