You can use a buckling analysis to calculate the critical load at which a structure will buckle, as well as the model's stresses, strains, and deformations at the onset of buckling.

In a buckling analysis, Creo Simulate calculates a buckling load factor (BLF) and mode shape.

See Buckling Analysis Overview for a more detailed description of and requirements for buckling analyses.
