Hoop Stress Buckling Load (External Pressure or Vacuum)
Hoop Stress Buckling Load (External Pressure or Vacuum) Formula |
||
| \( \Delta p_{max} \;=\; ( 2 \; \lambda \;/\; 3 ) \; ( t \;/\; D )^3 \) | ||
| Symbol | English | Metric |
| \( \Delta p \) = Change in Pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( \lambda \) (Greek symbol lambda) = Elastic Modulus | \(lbf\;/\;in^2\) | \(Pa\) |
| \( t \) (Greek symbol sigma) = Wall Thickness | \( in \) | \( mm \) |
| \( D \) = Outside Diameter | \( in \) | \( mm \) |
