Hoop Stress Thin-wall Section

Written by Jerry Ratzlaff on . Posted in Pressure Vessel

Hoop stress is the circumferential and perpendicular stress to the axis imposed on a cylinder wall when exposed to an internal pressure load.

Hoop Stress Thin-wall Section Formula

 $$\large{ \sigma_z = \frac{ p \; r }{ t } }$$

Where:

$$\large{ \sigma_z }$$  (Greek symbol sigma) = longitudinal stress (axial)

$$\large{ r }$$ = radius to point of intrest

$$\large{ t }$$  (Greek symbol sigma) = wall thickness

$$\large{ p }$$ = internal pressure
