Not sure if this would produce significantly different results, but is it correct to apply a negative y direction load to the entire inner surface of the hole? Would it be more accurate to apply the load to the half of the hole surface that is in the direction of the load?
As I note in the on-screen annotation at 1:30, I could have used a Bearing Load instead. The Bearing Load functionality uses a non-Hertzian distribution in which the load is applied over half the surface with the peak being in the direction of the force and tapers off to zero at the sides. Why did I use a regular Force/Moment Load instead of a Bearing Load? I don't remember. It might have been a wrong pick, but the point of the video was to show people how to run Buckling Analyses. Hence the on-screen annotation I added during the editing process. I have a separate video on Bearing Loads if you want more information regarding that command.
By both ends, I assume you mean top and bottom. Buckling requires that the part be under compression. It might be fastened at both the top and the bottom, but the load has to be transmitted from something through the fasteners into the part. Both ends aren't actually fixed. Load has to be coming from somewhere.
Actually, Creo Simulate uses Geometric Element Analysis and a proprietary solver. I know the branding can be confusing, but Creo Simulation Live is the one based on ANSYS.
Buckling mode 1 is where it’s likely to buckle first. But if you’re Buckling Load Factors are low, you might want to look at additional buckling modes to figure out how and where to stiffen the model. If your BLFs are high, the mode shapes can give you an idea where to lighten the model.
Thanks Dave!
Very informative!

Sir in case of both end fixed ,how to give proper boundary condition for buckling...im unable to do the same...kindly help...

Thank you for your response...
How accurate are creo simulate results compared to other leading FEA packages?
Since Creo Simulate uses ANSYS Solver, so I presume it will be as accurate as ANSYS could be.
Information on the verification models is available in the PTC Help section. As you will see there, the results are very close.

@@CADPLMGuy Thanks for the correction.
Sir can you explain the uses of buckling mode 1 or 2...im confused..
Buckling mode 1 is where it’s likely to buckle first. But if you’re Buckling Load Factors are low, you might want to look at additional buckling modes to figure out how and where to stiffen the model. If your BLFs are high, the mode shapes can give you an idea where to lighten the model.
@@CADPLMGuyThanks for replying...i got it..
Sir i want one video from you about how to create parametric model from step files, please guide us
I recommend you watch my video on importing and exporting STEP files.
