Hoop Stress Calculator

Hoop Stress Equation

$$ {\sigma}_h = \frac{P \cdot r}{t} $$ where:

σ_h = Hoop Stress (N/m² or Pa)

P = Internal Pressure (N/m² or Pa)

r = Internal radius of cylinder (m)

t = Wall thickness (m)

Property to Calculate:

Hoop Stress (σ_h):

Internal Pressure (P):

Radius (r)

Wall thickness (t):

Equation Assumptions

The wall thickness is much smaller than the internal radius (typically t < r/10).
The internal pressure is distributed uniformly.
The material of the vessel is homogeneous and isotropic.
