Eigenvalue Buckling 2

[dkeatley]

Can the eigenvalue buckling analysis determine whether the load applied will cause the model to buckle?

 

[bassmanjax]

Well, yes. If the load applied is equal to the buckling mode, then you'd get an eigenvalue of ~1.

*EDIT* I meant buckling LOAD not MODE ....

So eigenvalues less than 1 would suggest buckling?

 

[MrMyers]

yes, the alternative is to put a unit load as the applied load and your first eigenvalue is now your buckling load.

 

[bassmanjax]

Agree with MrMyers - that's exactly how I would normally do an eigenvalue buckling analysis.
