Radial Stress Thick-walled Section (Internal Pressure Only)
Radial Stress Thick-walled Section (Internal Pressure Only) Formula |
||
| \( \sigma_r \;=\; [\; p_i \; r_i^2 \;/\; r_e^2 \;-\; r_i^2 \;] \; [\; 1 - ( r_e^2\;/\;r^2) \;] \) | ||
| Symbol | English | Metric |
| \( \sigma_r \) (Greek symbol sigma) = Radius Stress | \(lbf\;/\;in^2\) | \(Pa\) |
| \( p_i \) = Intertnal Pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( r_i \) = Internal Radius | \(in\) | \(mm\) |
| \( r_e \) = External Radius | \(in\) | \(mm\) |
| \( r \) = Radius to Point of Intrest | \(in\) | \(mm\) |
