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