Hoop Stress Thick-walled Section (Internal & External Pressure)
Hoop Stress Thick-walled Section (Internal & External Pressure) Formula |
||
| \( \sigma_h \;=\; [ \; (p_i \; r_i^2) - (p_e \; r_e^2) - (r_i^2 \; r_e^2) \; ( p_e - p_i \;/\; r^2 ) \;] \;/\; [\; r_e^2 \;-\;r_i^2 \;] \) | ||
| Symbol | English | Metric |
| \( \sigma_h \) (Greek symbol sigma) = Hoop Stress | \(lbf\;/\;in^2\) | \(Pa\) |
| \( p_i \) = Internal Pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( r_i \) = Internal Radius | \( in \) | \( mm \) |
| \( p_e \) = External Pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( r_e \) = External Radius | \( in \) | \( mm \) |
| \( r \) = Radius to Point of Intrest | \( in \) | \( mm \) |
