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

\(\large{ \sigma_z = \frac{ p \; r }{ t } }\)   

pv cylindrical hoop stress 2Where:

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

\(\large{ r }\) = radius to point of intrest

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

\(\large{ p }\) = internal pressure
