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