Eigenvalue buckling analysis with ABAQUS using shell elements

[pfsm01]

Hello,

I am trying to obtain the buckling stress of a thin plate in ABAQUS modelled using shell elements. I loaded the plate with an edge load (force/length) and I obtain the eigenvalues. Do the resulting eigenvalues represent percentages of the buckling stress OR the buckling shell edge load?

Any insight would be much appreciated.

Thanks
