Longitudinal Stress Thick-walled Section (Internal Pressure Only)
Longitudinal Stress Thick-walled Section (Internal Pressure Only) Formula |
||
| \( \sigma_l = p_i \; r_i^2 \;/\; r_e^2 \;-\; r_i^2 \) | ||
| Symbol | English | Metric |
| \( \sigma_l \) (Greek symbol sigma) = longitudinal stress | \(lbf\;/\;in^2\) | \( Pa \) |
| \( p \) = internal pressure | \(lbf\;/\;in^2\) | \( Pa \) |
| \( r_e \) = external radius | \( in \) | \( mm \) |
| \( r_i \) = internal radius | \( in \) | \( mm \) |
