Shell vs Brick Element in Buckling?

Shell vs Brick Element in Buckling?

Shell vs Brick Element in Buckling?

(OP)
Hello:

I have a problem which deals with "buckling" of a rectangular cross-sectional boom. The boom has about 300 in length, 0.25 in thick, and 22 in side.

My question is: which type of element (shell vs. solid brick element) should be the most appropriate for this buckling problem?

Thank you for your insight.

Kind regards,

RE: Shell vs Brick Element in Buckling?

Shells. Solids would be more appropriate for the case where stress were non linear through each side wall, which is unlikely.
