Buckling analysis of a box

[frztrb]

Hi All

In buckling analysis of a Closed BOX , where only the walls are gonna buckle , how should I take into consideration the model ? a complete one ? and how would be the non buckling sides modeled and joined to the buckling walls ?

In a buckling analysis it's normal to consider the whole structure in case you miss out the first buckling mode. If the first buckling mode is one of the panels only then you could consider 90 or 45 degree symmetry, but at your peril.
