Hello everybody.
I was curious about the load cases selection for a linear buckling analysis (e.g. performing NASTRAN SOL105).
Normally I would prefer to have one criteria for selection of the 10 most critical load cases.
Is the Minimum Principal Stress in a FE-model a good indicator?
In the past a selection using the maximum compression in x- and y-direction (for a shell-element) and maximum shear doesn´t show all critical load cases (most critical load case was in the selected, but not the third critical).
In general I use structure with 2D-Elements and a mix of metallic and composite components.
Thanks for giving a good hint or tip.
