Previously, I was told by someone I trust well that a column can avoid buckling at the first critical load by applying the load "instantaneously" with a magnitude between the first and second critical loads. Of course nothing is instantaneous, so an idealization would be applying the load as a step function. I am an undergraduate mechanical engineer with no practical background with buckling failures and was hoping someone can shed some light on this problem.
I'm sorry I have few details or sources backing this question up, I have been trying to confirm it and have been unable to find it online.
Is this true? Can buckling be avoided at the first critical load by instantaneously applying a load between the first and second critical loads?
