Hoop Stress Buckling Load (External Pressure or Vacuum) Formula

\(\large{ \Delta p_{max} = \frac{ 2 \; \lambda }{ 3 }  \; \left( \frac{ t }{ D } \right)^3 }\)   

Where:

\(\large{ p }\) = change in pressure

\(\large{ D }\) = outside diameter

\(\large{ t }\)  (Greek symbol sigma) = wall thickness

\(\large{ \lambda }\)  (Greek symbol lambda) = elastic modulus
