Hoop stress refers to the stress that occurs in a cylindrical or ring-shaped object, such as a pipe or a barrel, due to the internal or external pressure acting in a radial direction. Understanding hoop stress is crucial in engineeringapplications as it helps determine the strength and stabilit...
p= pressure (from the head of liquid) d= diameter of the tank S=allowable stress E= weldjointefficiency (a type of safety factor) Using this equation it is easy to find the stress (S) or minimum required thickness (t) at any vertical position in the tank shell. The difficulty comes ...
As the requirement for pressure containment, the allowable hoop stressσh to be used in design calculations is to be determined by the following hoop stress criterion [1]: [2.5]σh=ηh·SMYS·kT where ηh = design factor (see Table 2.2, originally from B31.4 and B31.8) Table 2.2. Desi...
I would take sigma-h in E.6.1.4-6 to be hoop stress from hydrostatic head and pressure, not hydrostatic head alone. I would assume allowable stresses from API-620. Paragraph 5.5.6 doesn't allow 80% of yield, it allows 133% of allowable but not to exceed 80% of yield, and in most...
STRESS concentrationThe coiling process, crucial for winding long sheets of consistent thickness, often encounters challenges due to deformation induced by pressure and frictional forces on the inner mandrel and sleeve. This necessitates precise stress calculations to ensure operational safety ...

The mathematical model is derived from basic governing equation of thick cylinder. The appropriate boundary conditions are applied to each successive layer. Effect of number of shells on the maximum value of hoop stress is analyzed. Apart from this, effect of overall thickness of pressure vessel ...
The maximum radial stress equals the applied pressure. The stresses can be found from Eq. 8.14. The hoop strain at node 1 is εt = u1/r1 = 9. 964 × 10−5 in/in. The finite element radial strain approximation is εr=∂H1/∂r u1+∂H2/∂r u2. The constant radial ...
