HI,
I am doing an eigen value buckling analysis using ansys workbench. The FE model is 166° and not 180° (due to some assumptions).
The prestress is the elastic evaluation with primary loads (pressure and deadweight).
Will the multiplier from the 166° model be equivalent to the 360° model?? The load multiplier from 166° model is less than what I get from the ASME code (5.4.1) which means the structure is safe from buckling.
For 360°, I have to model and mesh again and apply the primary loads, solve again and then do the eigen buckling simulation to verify the load multiplier.
Is there any other way to do it?
