Principal virtual work theory for pipeline collapse and buckling

[akmalhisham75]

Dear All,

Does anyone here familiar with a theory called Principal Virtual Work (Equilibrium theory) ?
I read somewhere that with this theory, i could relate(for pipeline application - collapse & buckling) the components for ovalisation, external pressure and hoop strain.
Appreciate if somebody could guide me on this matter.


Thank you

Regards
