Question

Creo 7 vs Creo 10 Buckling Results

Hello fellow engineers,

 

Recently I updated from Creo 7.0 to Creo 10.0. I am in the middle of a project so maybe it wasn't a good idea. When re-running a buckling analysis that used to return a BLF of about 2.5 in Creo 7.0, now I get values of about 0.5! 

 

Has anyone noticed this pattern? I believe the new 10.0 version is overconservative, as I have done hand-calculations to verify the buckling mode and the plates are nowhere close to buckle. 

 

I believe the solver must have been updated. The model in question corresponds to a crane with a telescopic boom, where the contact pads (usually solids to allow for contact definition, non-linear analysis) are replaced by a beams (linear analysis).
