Buckling in surface geometry where the deflection but not the load is known.

Question asked by Reuben Symons on Mar 6, 2013

Hi I'm trying to optimise a piece geometry that makes up a surface that surounds a beam. The beam is a composite sandwich structure and I have used a piece of code to predict the deformation under the design load. I wish to optimise the surface to be as thin as possible without buckling. Ideally I don't wan't to simulute the beam on each iteration as this will add mesh cells and increase simulation time. Is there a way to limit the deflection to that calculated for the beam, so I can simulate the surface in isolation with the load essentially the force required to produce that deflection in the surface instead of the total load, most of which is taken by the beam.
