If I set up a simple vertical hollow tube (20mm OD, 16mm ID, 400mm long, aluminium) with a fixed constraint on the lower end face and a compressive load on the other which exceeds the critical Euler load (>>80kN) the simulation doesn’t obviously demonstrate Euler buckling. The only way to tell there…

Hello @Irving , thank you for your feature request! As @jousefm mentioned I will keep you up to date. We will also collect more feedback from the rest of our users in the near future! I keep you updated! Best Alex

Good evening @irving , this is already on the roadmap of SimScale as mentioned by @ahmedhussain18 in this post . @afischer or @dheiny might give you an insight into that upcoming feature. Cheers, Jousef

Thanks for that information & link. I note you consider this a 2d problem but that’s just an artifact of the way that @alabrazi presented his problem. Mine is ultimately a 3D problem as the columns are legs to a structure. There is a more general point here - the representation of failure modes in…

Hi @irving , that is right. I was just referring to buckling in general (2D as well as 3D). Concerning your question about the representation of failure, consider this post of @rszoeke : Show overload of a structure Does that somehow cover the wishes you have for the representation? Best, Jousef …

@Jousef Thanks, that’s a very useful approach. It would be nice, in the future maybe, to see failure graphically represented in the WarpByVector filter (or, better, a dedicated ‘Failure’ filter) based on the material properties and a ‘safety factor’ value. rgds, Irving

I’m also interested in same, can you also notify me if this feature is on track?

Hi @gkotelnytskyy ! I will definitely keep you up-to-date, no worries! :slight_smile: All the best! Jousef

Hi @gkotelnytskyy , please don’t forget to vote for this feature here: Buckling analysis feature addition request Best, Richard

Is there some workaround before the feature is added. I.e. applying small lateral force to the column – would it work to the same effect?

Hi @gkotelnytskyy , as long as you know in which range the critical load will be. this might work. I made a small example, with a fixed end + pinned collumn under compressive load: Buckling Test by rszoeke | SimScale From hand calculations the critical load should be about 30.31KN. The nonlinear …

Hi @irving,

I already transferred your feature request. @afischer will keep you up to date.

Enjoy your stay here and have a nice weekend!
