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:

σ_h = p d / 2 t (1)

where

σ_h = 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:

σ_l = p d / 4 t (2)

where

σ_l = longitudinal stress (MPa, psi)
