Hi,

I am currently running buckling analysis in SW simulation. My geometries are simple, they have rectangular cross sections for the majority, except a taper at the top and bottom of the structure. I've attached images of the simulations for reference.

Simulation 1 (image 1): Did a buckling analysis through the study advisor (but not the one where it assumes it to be Euler's buckling mode). I get the correct deformation and a 'load factor' that corresponds very well with a rectangular beam of simliar length in my own Euler's buckling analysis. The problem here is I cannot create a stress plot from this analysis.

Simulation 2 (image 2): Same loading constraints however it is *not *a buckling analysis. It is just a fresh new simulation with no specificity. I can get stress plots out of this, but then again my beam does not buckle.

Is there any way to combine simluation 1 and 2 so I can do a buckling analysis but still see the corresponding stress plot? I am basically trying to optimize the design by removing material while maintaining a threshhold load factor value.

Thanks in advance for your help,

Omid

You are a long way from home. Buckling is a stiffness problem or more correctly a lack of stiffness which leads to sudden collapse. It isn't a stress problem - hence no plot in a eigenvalue extraction method for linear buckling. If you want to reduce the weight take material out where it has a low impact on lateral stiffness, and the make sure it has the stress margin for whatever the load case is. You can do a multiple load case optimiztion quick enough if you have the software.
