Stress in Thin-Walled Cylinders or Tubes

Calculate hoop and longitudinal stresses in thin-walled cylinders or tubes subjected to internal pressure. This tool applies when wall thickness is less than 1/20 of the tube or cylinder diameter.

Calculator

Inputs

Internal Pressure (p) (MPa)

Internal Diameter (d) (mm)

Wall Thickness (t) (mm)

Results

Hoop (Circumferential) Stress-- MPa

Longitudinal (Axial) Stress-- MPa

Stress Type	Formula	Value (MPa)
Hoop Stress (σh)	p × d / (2 × t)	outputs.hoop_stress
Longitudinal Stress (σl)	p × d / (4 × t)	outputs.longitudinal_stress
