Buckling

[SKS2022]

Hello!

I am working on a thermal buckling analysis of a beam using Ansys as a benchmark.

I was wondering is it possible to model a beam where on one edge temperature T1 is applied and on another edge temperature T2 is applied. Meaning, we have a model with linear temperature rise along the beam length and the aim is to calculate critical buckling temperature (eigenvalue).

How can this be done with Ansys Workbench using shell elements?
For uniform temperature rise od the beam, thermal buckling analysis can be done easiliy with temperature condidion of the body in Static Structural connected to Eigenvalue buckling.

Thank you,
Sandra

I would expect such a simple problem could be solved by software, but the problem is easily solved by hand methods. I am wondering however, where the assumption of linear temperature rise would constitute realistic conditions in a real structure.

If I add composite materials, problem is not easily solved with hand methods.
I am still trying to find out how to model temperature rise along the beam length.

Thank you for your comment.

Maybe a description of your problem would help. I believe is is fairly easily solved using hand methods, even with composite materials.
