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