Stresses in Thin-Walled Tubes or Cylinders
Hoop and longitudinal stresses thin-walled tubes or cylinders
Sponsored Links
When a thin-walled tube or cylinder is subjected to internal pressure a hoop and longitudinal stress are produced in the wall.
Hoop Stress
The hoop stress can be expressed as:
σh = p d / 2 t (1)
where
σh = hoop stress (MPa, psi)
p = internal pressure in the tube or cylinder (MPa, psi)
d = internal diameter of tube or cylinder (mm, in)
t = tube or cylinder wall thickness (mm, in)
Longitudinal Stress
The longitudinal stress can be expressed as:
σl = p d / 4 t (2)
where
σl = longitudinal stress (MPa, psi)
